NEC – National Electrical Code – changes in 2011 upgrade electrical safety
Posted at 11:34 am by admin in electrical safety
When electricians and inspectors talk about being “up to code,” they mean in compliance with NEC. Revisions every three years improve safety and address emerging technologies
DENVER, CO – The National Electrical Code, NEC, is a complete compilation of rigorously adopted standards for the safe installation of electrical wiring and equipment – in all settings, from residential and commercial, to industrial, outdoor, health care facilities and more – throughout the United States. While voluntary, the NEC has been adopted by most governmental jurisdictions throughout the land as a single, standardized source of electrical requirements, and its recommendations and procedures are used by inspectors to verify compliance.
When electricians, contractors and building department refer to something electrical as “being up to code,” it is NEC they are talking about.
The NEC is part of the National Fire Codes that were developed and are maintained by the National Fire Protection Association, and as such NEC is also sometimes referred to as NFPA 70. This whole codification began back in the 1890s in a limited area back east, and has been joined by other regional electrical code initiatives over the years to create a national standard.
However, “standard” may be too strong a word. With input by a wide variety of stakeholders, the NEC is under constant discussion, and every three years the code is revised and new standards issued. The NEC 2011, released just last year, is the latest edition of the nation code, and it comes in at a whopping 870 pages in its softbound edition (it’s also available as an electronic PDF file. Visit NFPA for ordering and pricing). The next revised NEC standards are due in 2014.
The NEC is certainly important to the average homeowner, however much of its provisions and revisions are meant for the professional audience of electricians, electrical engineers, contractors and the like. While there are changes to the code every three years, there are no requirements for the homeowner to automatically be in full compliance. In fact, the homeowner can make minor changes – changing a plug or a switch, for instance – without regard to the code, and keep things in their own home the same as they are.
Remodeling, however, can change everything. In any remodeling project the NEC will have to be followed to the letter of the code or the project will not pass the required round of inspections. Plus, if it’s a major remodeling project – in some jurisdictions defined as 70% of the home, everything electrical in the home will have to be brought up to code.
We here at Allstar Electrical Services, a professional, licensed electricians, keep completely up-to-date on the NEC and all of the changes instituted every three years. As mentioned above, the code is now 870 pages, and just going through the changes in the 2011 updates is a very laborious undertaking – with which all of us are current.
Unless you are an electrician, or one of the related professionals mentioned, going through all the new code changes is an unnecessary and time-consuming activity – and much of it if fairly esoteric or industry-specific, to wit:
•New Article 694 has first-time requirements for small wind electric systems.
•Revised Article 625 includes updates on safe battery charging for plug-in hybrid vehicles that reduce the risk of explosion.
•Revised Article 705 covers interconnecting generators, windmills, and solar and fuel cells with other power supplies.
•New Article 840 addresses the increased demand for broadband communications systems with requirements for wireless, routers, and wireless disconnects.
New requirements focused on workplace safety include:
•Means to reduce incident energy (240.87)
•Labeling at subpanels to identify feeder supply source (408.4(B))
•Disconnecting means for transformers (450.14)
` *New Article 399 incorporates requirements for overhead distribution systems for large electrical system users, such as school or business campus settings.
For the homeowner, the new NEC standards have a lot to do with the use and placement of GFIC – ground fault interrupter circuits, those special plugs in bathrooms and kitchens (near water sources) that feature the reset buttons – and also for the type of receptacles, plugs, that protect, for instance, little children from sticking things into them. Here’s a general overview of some changes in the NEC for 2011 having to do with the home:
Bathroom Electrical Code:
- Only install GFCI (ground fault current interrupter) receptacles in bathrooms.
- There must be a receptacle within 3 feet of the outside edge of sink basin.
- No receptacles face-up on countertops.
- Receptacles must be on at least one separate 20 amp. branch circuit (because this receptacle usually powers high-wattage devices like hair dryers).
General Rooms:
- Wall receptacles every 12 feet.
- Receptacles on any wall space more than 24 inches wide.
- Hallways more than 10 feet must have at least one receptacle.
- Foyers, which used to be classified as hallways, now have their own receptacle distribution code.
Kitchens:
- All countertops receptacles must be GFCI.
- No receptacles more than 20 inches above countertops. Exceptions are for the physically handicapped and for islands or peninsulas where this is not possible.
- Receptacles above all countertops 12 inches or wider.
- No face-up receptacles.
- At least one receptacle for islands or peninsulas.
- At least two branch circuits must supply the countertop receptacles.
There are also some new rules for receptacles and lighting in garages, attached and free-standing, and other outbuildings that have electrical power – like tool sheds wired for recharging electrical power tools, for instance.
Once again, the homeowner not undergoing a major remodeling is not required to meet the new standards, only when changes are made. It is, obviously, wise to call in a professional electrician to accomplish these tasks because we understand the code requirements and can easily handle these upgrades and improvements.

Be Prepared with Winter Power Outage Tips
Posted at 9:58 am by admin in commercial electrical tips.residential electrical tips
Allstar Electrical Services, serving metro Denver for over a decade, reminds consumers that winter power outages often occur and taking precautions will keep people and their homes safe
DENVER, CO – Already this winter there have been power outages reported in many jurisdictions across the country, particularly in New England, and while some of them have been short-lived, a few hours, some areas have experienced no power for several days.
Colorado has been spared a winter power outage as yet this winter, but these occurrences do happen in the state and people should be prepared. Most commonly, power outages in the winter are weather-related, when severe storms bring down power lines or blow out local substations, or they can be isolated to even a single home if the wires come down. They can last for a matter of a few minutes or they can go on for several hours or even days depending on the severity of the outage.
At Allstar Electrical Services of Denver we are experienced with power outages, both localized and widespread, and over the years we have developed a few Winter Power Outage Tips to help our customers and the public in general in case of a problem with the electrical supply.
In the event of a loss of power in your home or in a business location, the first thing to check is if the power outage is just your property or if it is something affecting an entire area. A quick check of the neighborhood will give you a good idea of whether the outage is just your property or a bigger problem. If it’s just your property, then check your circuit breaker to see if you have a blown fuse and/or circuits out, and try to switch them back on or replace fuses (it’s always a good idea to have extra fuses on hand in this event). If it is more widespread, it is recommended to check with the local utility company – call the utility, but don’t call 9-1-1 as that is reserved for emergencies. The local utility should have information on how long it will take to restore power.
Here are our Winter Power Outage Tips:
Before a power outage occurs.
- Be prepared. You never know when a power outage might occur, so it is a good idea to be prepared in advance. Make sure you have batteries for flashlights and battery-operated portable radios on hand so you’ll have a light source and some communications.
- Alternative heating sources. A power outage will keep most furnaces out of commission for the duration, so if you have a gas-powered fireplace or wood-burning stove or fireplace, make sure you keep adequate fuel on hand. Do not use a kerosene heater or a barbeque grill for heating as these devices inside a home will spread toxic fumes.
- Insulation. Make sure your home is well insulated and that doors and windows are caulked. Storm windows or windows prepared with winterization kits are also a good idea. This will help hold in the existing heat for as long as possible. Also, make sure water pipes are adequately insulated.
- Water shut-offs. Know where the water shut-off valves are so in the event of an extended power outage you can shut the water off and be prepared to keep the pipes from freezing. (If an outage occurs and is predicted to last an extended period, shut off the water and open the spigots throughout the house to drain pipes.)
- Check the garage. Know how to manually operate a garage door. Instructions for overriding an automatic garage door opener come with the device. In the event that you have to leave the house you want to get your car out.
During and outage:
- Stay away from downed power lines. Storms often bring down power lines and you don’t want to touch them or be near them when the power comes back on.
- Listen to your battery-powered radio or TV, especially for news at the top of each hour, to find out when the power might be restored.
- Dress warmly. Wear layers, including a sweater, sweatshirt or even a jacket. You lose heat through your hands and the top of your head. Wear gloves and a knit hat, not just a baseball cap.
- Avoid opening the refrigerator. Food in the refrigerator and freezer will last longer if you keep the doors shut as much as possible.
- Unplug major appliances. When the power comes back on, all of those appliances can create a drain or power surge, which can harm sensitive equipment. To avoid a power surge when the electricity returns, turn off computers, TVs, stereos and other unnecessary electronic equipment at the power source. Leave a light on so you’ll know when the power is restored.
- Generators. If you have a generator, do not connect it to your home’s power system unless it has been properly installed and disconnects you from the main power grid when it is operating. If you do not disconnect from the power grid, you can be sending electricity back down the lines; not just to your home. That could be deadly for power company workers.
- Check on your neighbors. The elderly or those with medical conditions may need some assistance. If you have to go out, drive carefully. Remember that traffic signals may be out during a power outage. Consider each intersection to be a four-way stop and drive defensively.
- Be careful going out. A widespread power outage will most likely impact traffic signals and street lights, so take extra cautions if you must drive around.
- Check the radio. Keep that portable, battery-powered radio at hand and check news reports (usually at the top of the hour) to keep apprised of the power outage situation and utility company reports.
Most often power outages will only last a short time, from a matter of minutes to a few hours. However, if it is going to be a long time, check with friends to see if they have power and can take you in, or in some cases local emergency shelters are set up to help. Being caught in the cold for an extended period of time can be dangerous, so be prepared to evacuate to safe location if necessary.
For all of your electrical needs, from minor repairs and additions to emergency work, both residential and commercial, call on Allstar Electrical Services, serving the Denver metro are for over a decade. For complete information call 303-399-7420.

Simple steps can often significant reduce commercial office building energy consumption
Posted at 4:59 pm by admin in commercial electrical tips
Utility costs can rack up for than 30 percent of a commercial property’s operating expenses. Finding ways to save on electricity and natural gas can pay dividends right away
DENVER, CO – As anyone who owns, operates, manages the costs of commercial office buildings knows, energy fees lead the list of recurring expenses year after year. What’s more, energy costs are often variable what with changing weather patterns, cold spells and heat waves, and the inevitable requests from utility companies for higher rates on electricity and natural gas.
According to statistics amassed by various energy efficiency organizations, including the Energy Star program within the U.S. Department of Energy, utility costs in commercial office buildings rack up nearly 30 percent of a property’s annual operating expenses, mostly in electricity and natural gas fees. Since the average office building in the U.S. is estimated at 15,000 sq. ft., these utility costs can easily exceed $40,000 per year, with obviously some weather and pricing variables by region of the country. Here in Colorado we experience both hot and cold weather, of course, so we are fairly balanced in our energy use, but we enjoy overall lower humidity than the country in general, which puts less pressure on our air conditioners. We also have more wintertime sunshine which mitigates some heating costs.
Still, energy consumption in Colorado office buildings is a significant contributor to operating expenses, and there are several ways in which building owners and operators can attack those expenses and save as much as 30 percent on energy bills.
Here at Allstar Electrical Services, we have been in the business of providing a full range of electrical services for over a decade, including commercial and industrial electric where we have vast experience in new-build, retrofitting existing buildings, and in updating commercial properties with new electrical fixtures and service to meet stringent energy use requirements. Our licensed electricians have worked with LEED and Energy Star certified building projects in both the design and build out of new properties, and in the certification of existing structures in remodels.
In other words, we have learned a great deal about commercial property energy consumption and, more importantly, how to lower electric and natural gas utility bills. This article represents years of energy-saving involvement.
First and foremost, the best thing any building operator can do in the battle to lower utility costs is to get a full energy audit done on the property. These audits are conducted, for a fee, by engineers specifically trained or experienced in energy consumption in buildings, and often local utility companies, such as Xcel Energy, partner on such audits and offer certain rebates and financial incentives for conducting them and/or implementing recommendations. A building energy audit covers everything, from HVAC system analysis and energy status of current indoor and outdoor lighting systems, to heating and cooling use patterns and how building tenants use effects energy usage. And, of course, everything in between.
Of course, the biggest users of energy in the office building are lighting, cooling and ventilation on the electricity side (about 60 percent of overall energy consumption), and heating on the natural gas side. Because of this impact, these are the areas to begin with for energy use reduction.
As simple as it sounds, nearly every energy audit we’ve ever seen concludes that the largest impact any building owner/manager can have on electricity usage is just turning things off. It’s like teenagers left alone in the home – every light on, every TV, every appliance. Like being Dad the bill payer, simply going around a building and hitting the switches is an important energy-saving strategy.
Many building owners institute company policies on energy use and turning lights off, and in many cases this will involve working with tenants, and sometimes multiple tenants with differing work schedules. To help out, there are some relatively easy electrical system changes that can help. Lighting systems can be on timers programmed to go off at a certain time (like 7 p.m. in wintertime), which can be easily overridden by tenants who work late. By code, there will be a few designated fixtures and lights throughout the building that never go off for safety reasons. In non-regular-work areas, like rest rooms, kitchens, storage closets, etc., it would be wise to install motion- or door-detector that turn lights on for a pre-determined time when someone enters the room, and then go off automatically when idle.
Among more expense options, but offering significant savings as well as a variety of rebates and tax incentives, is changing the lighting systems in the building to more energy-efficient lighting. For instance, many building which have been in place for several years utilize T12 fluorescent light tubes, soon to be discontinued, but replacing them with Super T8s or T5s can not only drastically slash to electricity use, but in many cases deliver better lighting characteristics in lumen output and color. Building owners should consult with lighting experts as there are many alternatives for interior, exterior and parking lot lighting solutions these days that offer better lighting at significant energy savings.
For electricity use on the cooling and ventilation side of the energy-consumption ledger, once again the easiest solution is generally very simple: make sure the HVAC units themselves have regular maintenance, clean coils, and that the filters are changed to the specifications set forth by the manufacturer. If the units themselves are older than 10 years, replacement may be a good option as the newer models of air conditioners, furnaces and ventilators are significantly more energy efficient with no discernible difference in capacity. An energy audit will help determine pay-back periods for any improvements, and of course rebates or any tax incentives will improve the pay back.
Window treatments can also help to significantly reduce energy consumption in both cooling and heating. There are new commercial windows on the market with photo-sensing properties that shade heat-producing sunlight in the warm months and let warmth in in the cold months, and there are window films that can deliver some similar properties for a lower cost. Engineers also recommend lighter roofing materials in some cases that can reflect sun warming and not contribute to heat build-up; i.e. painting or covering a roof with white instead of black.
And don’t forget age-old techniques for heating and cooling management like deciduous trees planted on the south and west faces of a building that shade the property in the summer and let the warmth in during the colder months.
In the colder months managing heat levels in a building is a superior energy-management technique. Most newer properties with have programmable thermostats and multiple sensors for temperature management, but older properties could benefit by upgrading to such a system.
The truth is that energy management these days is a highly sophisticated endeavor for commercial properties, and we haven’t even scrapped the surface here. There are lighting design systems, for instance, that utilize daylight measurements and reflectors than con contribute to savings, the installation of different doors and/or windows, and even something like moving the main entrance from the north face to a south face that can help. An energy audit, as we said, is a great place to start the investigation.

Energy efficient high-bay lighting systems in commercial facilities may qualify for significant rebates and tax incentives
Posted at 5:00 pm by admin in electrical upgrades.high bay lighting.Light Fixtures
Changes in lighting regulations and energy-savings plans could make retrofitting warehouses and industrial operations a quick pay-back and utility cost savings proposition
DENVER, CO – Commercial operators of warehouses and industrial facilities can enjoy significant rebates and tax incentives for switching out antiquated high-bay lighting systems by the end of 2011, and this is on top of energy-cost savings of up to 50%.
Allstar Electrical Services of Denver has been providing top-notch commercial electrical systems retrofits and new builds for over a decade in Colorado, and is an expert at replacing whole-facility lighting systems that meet the demands of Xcel Energy rebate programs and government tax incentives.
Many warehouses and industrial facilities utilize HID (high-intensity discharge) lamps or the common T12 fluorescent lighting arrays for high bay and large-area lighting solutions, both of which are less efficient energy users for these applications than more modern lighting systems. Indeed, the U.S. Department of Energy in 2010 began phasing out T12 fluorescent lights and the manufacture of the most common forms of T12 lights will cease as of July 2012. It is highly recommended that operators of large-are facilities retrofit their buildings with T8, T8 Super or T5 HO systems.
Xcel Energy in Colorado is offering a great rebate program for such retrofitting, providing bonus rebates of up to 50% of the cost of the project through the end of 2011. When you add in up to 50% savings on utility bills for operating such systems versus the old systems, the pay-back on the purchase and installation costs can be as little as three to seven years. Plus, since the T12s are being phased out by mid-year 2012, the cost of maintaining an older lighting system will significantly increase. These special rebates are a bonus on top of existing Xcel Energy rebates for switching to more efficient lighting systems in commercial facilities, so the savings could even be greater: all rebates cannot exceed 75% of the cost of the new lighting.
In addition, under provisions of EPAct of 2005 (Energy Policy Act) owners or tenants in commercial properties can enjoy generous tax deductions for upgrading lighting systems with the Energy Efficient Commercial Buildings Tax Deduction, a special financial incentive designed to reduce the initial cost of investing in energy-efficient building systems via an accelerated tax deduction. Under this provision, the owner (or tenant) can upgrade a building’s lighting system to qualified levels to earn the deduction, capped at $0.60/square foot. For example, in a 100,000 square foot warehouse facility, the deduction would amount to $60,000; for a business in the 35% tax bracket, that would reduce the tax burden in the year of retrofitting by $21,000. The provisions of the tax code these incentives fall under are known as EPAct 179D deductions, and for the moment they are scheduled to expire on January 1, 2014 (they have already been extended twice).
The size measurement of fluorescent lights refers to the diameters of the tubes themselves. T12 tubes have a diameter of twelve eights of an inch, or 1 ½ inch, while T8 are one inch in diameter, and T5s come in at 5/8”. This matters because the thinner bulbs are more energy efficient, and thus save on utility costs.
Lighting designers, and expert commercial electricians like Allstar Electrical Services, are very adept at choosing the proper lighting systems for each facility. In general terms, T8 systems are used for mounting heights under 20 feet, with T5 used when mounting heights exceed 20 feet, and there are also T8 Super and T5HO (high-output) lights that provide greater lighting capacities at a higher cost. Designing the proper system for any facility may involve mixing the fixtures, so that, for instance, the lower-cost T8 fixtures and bulbs will be used in office settings, and areas in the warehouse requiring higher lighting capacities would use one of the other choices.
Beyond the rebates, tax incentives and energy savings that come along with a new lighting system for warehouses and industrial facilities, another advantage of going to a T8/T5 fluorescent lighting solution is the relative ease of retrofitting and installation. In other words, Allstar Electrical Services can get a new lighting system up and running with minimal downtime in the facility’s operation cycle.
Owners and developers of new commercial properties should also take note that such high-efficiency lighting systems in new construction also may qualify for rebates and tax incentives.
As with all rebate and tax incentives on lighting systems, there are many specific qualifications that must be met in order to claim the benefits, and these vary by project. In some cases, for instance, the plan must be submitted to Xcel Energy in advance for pre-qualification, and of course tax professionals may need to be consulted in order to meet the accounting procedures for claiming deductions.
Allstar Electrical Services has worked with a variety of commercial facility managers, contractors, architects and tax professionals on lighting projects that qualify for rebates and tax incentives and can plan such a project to meet all of the requisite qualifications.

Electrical service upgrades for homes handle new demand and provide comfort and safety
Posted at 2:12 am by admin in electrical upgrades.home improvement.Remodeling.Saving Money
Many homes even 10 years old, but especially older homes, have inadequate electrical service and wiring to handle the explosion of electric conveniences that define modern life
DENVER, CO – What with the real estate market continuing in the doldrums as a result of – and most likely the cause of — the recession, many homeowners in Colorado are deciding not to sell, but rather to do some remodeling to make their current home more livable for the long haul. Why not add a room, build out a basement, put in a new kitchen, expand the garage, or redo the landscaping? Many homeowners find that their existing homes, with a little work, can be just as comfortable as a new one and even more valuable.
At Allstar Electrical Services we get called in all the time to assist with the electrical needs of these projects and we often find that the electrical system is incapable of handling the increased demand.
And it’s not just for remodeling projects: even when a homeowner wants to add a few new outlets, install a swamp cooler or hot tub, or add exterior lighting for beauty and security, electrical demand becomes a key issue.
The reasons are many, but they start with the changing electrical codes over the years and the simple fact that modern life is far more based on electrical conveniences that far outstrip the electrical demand anticipated by builders – and code writers – even in 10-year-old homes, much less those that are decades old.
Plus, the issue of electrical demand also arises for those homeowners who actually decide to place their homes on the market: in many cases, especially in older homes, the electrical system in the home is so out of date, and out of code, that it needs to be upgraded before the home can even be offered for sale.
A residential electrical upgrade can not only insure that a home is capable of handling all of the electrical demand now and into the future, but it is also an investment in the safety and comfort of the home’s occupants.
It all begins with the circuit box, or the service panel, the centerpiece of any home’s electrical system and usually located outside on the back of the home where the power lines from the utility enter the structure. More than 40 years ago the basic standard for most homes was 60 amp service, and this was more than adequate for smaller homes back then that lacked any large-electrical-demand appliances like air conditioners. The standard switched to 100 amp service in most areas by the 1970s, as the size of new homes increased and more appliances came into vogue.
Today the basic standard, and code in most areas, is 200 amp service. It’s not hard to imagine why: A/C, or at least a swamp cooler, is now almost a given in most homes and literally all new homes, kitchen and bathroom appliances have exploded with an “app” to handle just about any cooking or grooming task, and the sheer boom in home electrical conveniences as computers and related hardware, as well television and entertainment systems replete with myriad add-on devices would boggle the imagination of home planners even 20 years ago. Electrical demand in the home has, quite obviously, expanded exponentially.
While homeowners themselves, with a little handy background, can perform some minor electrical upgrade tasks in their home – new plugs and switches, for instances – it is not recommended that anyone other than a professionally licensed electrician tackle something as complicated, or potentially hazardous, as a service panel upgrade. We at Allstar Electrical do these upgrades all the time, and without fail it drastically improves the electrical operation in any home and provides enough electrical capacity for remodeling projects, new appliances, and any and all lighting projects.
Another area where homes, and again especially older homes, need electrical system upgrades is in a home’s wiring. Wiring standards, and even the type of recommended wire and insulation used, have changed a lot over the last 10 to 20 years, and electricians regularly find wiring areas needing an upgrade even when performing minor repairs and installations. This frequently occurs when adding additional outlets and switches to accommodate a new entertainment system with a large-screen TV, digital recorder, sound system, cable/digital/HD boxes, DVD players and the like. Electricians often find that the room selected for the entertainment area lacks the wiring necessary to handle the job and that replacement wiring is called for.
Upgrading a home’s electrical system is a great investment in the comfort, safety and convenience of any home, and is an excellent and even essential platform for such wish-list items as a hot tub or spa, A/C unit or swamp cooler, and exterior lighting, and, of course, for any remodeling project that will add size to a house. When considering an electrical upgrade, have a licensed electrician perform a home system inspection to ascertain what level of service currently exists, how old and/or up-to-date the wiring may be, and be sure to anticipate the kind of add-ons and wish-lists that involve electrical usage so the home will be capable of handling anything electrical. The inspection will establish the baseline and help any homeowner decide on the type and extent of an electrical upgrade required.
For all of your electrical service needs, from minor repairs and outlet installation to major upgrades and remodeling projects, call of Allstar Electrical Services, serving the metro Denver and Front Range of Colorado for over 11 years with fully licensed professional electricians.

Electrical generators protect businesses and homes; expert maintenance and repair is a must
Posted at 2:08 am by admin in electrical maintenance.electrical safety.home improvement
Power outages in the US are on the rise, and electric generators can keep business running smoothly and protect homes. Keeping the generator in good repair requires an expert to ensure it works when needed
DENVER, CO – For many businesses, and even many homes, an electrical outage of more than a few minutes could present a severe problem, including downtime from operations, overheating or a too-cold environment, security breaches, personal safety issues, spoilage of food stuffs, and a variety of other issues.
Imagine being a hospital, day care center or long-term care facility; if a power outage hit for any length of time, lives could be in the balance. Retail outlets and office environments losing power would be virtually shut down for the duration, and even in homes where people work, or in winter during severe cold snaps, and where refrigerators and freezers protect valuable food stores, a major power outage could be a major inconvenience or a costly and potentially dangerous situation.
Wide varieties of commercial and industrial properties, and a growing number of American homes, have installed automatic generators that can seamlessly provide all of the power necessary, or at the very least enough power for essential services within the property, in the event of an electrical service interruption. Since a generator is like an insurance policy – there for an emergency situation – it is highly important that when called upon, an electrical generator performs as advertised. Most of these units contain regular automatic testing cycles that go a long way to ensure a property owner that the generator will work when the power goes down, but it’s important to observe a regular maintenance program to keep a generator system ship-shape, and to have an expert on call to make necessary repairs in the event of a failure.
Allstar Electrical Services is just such an expert. As licensed, professional electrical contractors in Colorado for commercial and industrial properties, and well as residential service and repair, we have installed hundreds of electrical generators for all types of properties, and we are fully versed in the necessary maintenance programs and generator repairs. And since we specialize in 24-hour emergency service, an electric generator on the fritz in most cases can be repaired before the power is restored.
The issue of power outages is, in fact, a growing concern. They are associated with such natural disasters as floods, hurricanes and other storms, of course, but power failures not associated with such events are on the rise nationwide. According to a report in an online4 edition of CNN Tech from a year ago, there has been a “frighteningly steep increase in non-disaster-related outages affecting at least 50,000 residents“ recently. In fact, the story noted, from the beginning of the 1990s to the end of the first decades of the 2000’s, such blackouts have increased 124 percent. From just 41 blackouts nationwide over the 5-year period 1991-95, and 92 such incidents between 2001 and 2005, utilities across the country reported 36 such outages in 2006 alone.
The reason for the increase in non-disaster power outages is ascribed to two main factors: 1) the aging infrastructure grid in the United States electrical system that is, essentially, operating on 1960’s and ‘70’s technology; and, 2) the concomitant growth in the U.S. population over the period (the estimated US population in 1980, for instance, was 226.5 million people, while the 2010 Census showed that 308.7 million lived in the country – an increase of a whopping 36%.)
So, obviously, having a back-up source of electrical generation in case of an electrical emergency is not just possible, but highly probable.
Electric generators come in a variety of forms and sizes. There are, of course, portable generators, usually operated by gasoline that depending on the size can handle the emergency needs for electrical power for a few electrical devices.
For most buildings, however, electricians install generator units capable of handling whole-building electrical needs. They can run on natural gas, gasoline, diesel, or propane or LPG, liquefied petroleum gas. These units typically require a transfer switch, sold separately, that automatically switches on the generator in the event of a power outage to the building’s main circuit box(es), that maintains a nearly seamless supply of power. The transfer switch also shuts down the generator and returns the power supply to traditional channels when power from the utility is restored, again in a fairly seamless manner. In other words, the building operator or homeowner really doesn’t need to do anything if the power goes out – which is a good thing if it happens in the middle of the night on a very cold period of time.
These switches can also be programmed, along with the power supply generator itself, to perform periodic test – generally weekly – to ensure the system is working properly.
As with any piece of complex equipment, however, particularly one located outdoors and subject to the weather, deterioration, blockages, freeze-ups, and unexpected service issues arise. Like air conditioners, furnaces, swamp coolers, and automobile engines (which generators most resemble), regular maintenance is required to make sure the machine will operate properly when needed. Just as car owners take in their cars periodically for a tune-up, check-up and winterization, having a trained technician check out a generator each year will offer peace of mind.
If there is a failure, having a generator technician with immediate access to the required parts and the necessary expertise to do the repair now is also a necessity. After all, the generator is there to perform in case of an emergency; if it fails when called upon, it is an expensive – and unnecessary – power outage.
Our clients with generators on their properties know Allstar Electrical Services will be there with expert maintenance and timely repair services should the need arise. Call 303-399-7420 for complete details.

Home Improvement Tips: Wiring Switches
Posted at 9:36 am by admin in DIY.electrical safety.home improvement.Remodeling
Simple projects like replacing switches can be done by homeowners, with caution
Working with electricity can be hazardous, but some minor projects can be accomplished by the DIYer; however keep in mind the rule of thumb: when in doubt, call a professional
DENVER, CO – Many people — and let’s be honest, especially men – fancy themselves handy enough to tackle small repair, replacement and enhancement projects like installing light switches, receptacles and lights. Or in some cases it isn’t the DIYer complex, but rather the aversion to spending the money on a professional electrician that drives people to Do It Yourself.
The truth is that simple electrical projects in and around the home can be done relatively easily by the homeowner, and the easiest among these involve installing or replacing light switches, receptacles (“plugs”) and fixed lights connected to switches.
Like everything else involving electricity, extreme care should be taken at all times. Even for the most minor of projects, it is wise to purchase a simple circuit tester to afford some assurance that the circuit being worked on is indeed off. There are also relatively inexpensive testers available at most hardware stores that can identify the “hot” wires and measure the amperes being used in the circuit.
If you are going to add or replace a light switch in a particular area, the paramount first thing to do is to identify the circuit that is supplying the power to that area so you can switch off the power supply at the circuit breaker. If you are installing a new switch, light or receptacle you’ll have to identify the circuit being used to supply the power and make sure it is turned off at the circuit breaker.
The easiest job, of course, is simply replacing a switch, light or receptacle. You take the old one off and rewire it in the same way. Make sure the switch is placed in the box so that “on” is up and “off” is down. For a switch, the black or “hot” wire from the power source leads directly to the bottom connector on the switch, and the white “neutral wire goes on the top. There are generally two ways to make these connections: most modern switches have both a screw (where the stripped wire is wrapped around and the screw tightened), and there is a hole on the back of the switch where a ½-inch stripped wire can be inserted. Then the wire leading out to the light is attached in the same way (wrapped around the screw or inserted in the hole), from the other side, with the “hot” or black wire leading out from the top connection. If the box is metal, attach the ground wire to the box; if it is plastic take all the other wires and cap them off with an electric screw cap.
If you are pulling wires to connect a new switch the job is much more difficult. Pulling wires through an existing wall is a task better left to a professional. If you are placing such a switch in a new wall or one that will be covered with drywall later, then you’re in luck. Make sure the circuit if off and connect all the wires in the same way. For receptacles (“plugs”) the connections are very similar and should be just as easy. Switches should be 48 inches off the floor for convenience and it is recommended that they be placed in easy-to-reach spots that won’t be hidden by furniture.
When it comes to wiring light fixtures so they work off the new switch, all these same guidelines apply. You can attach the wires on an existing light switch the same way they came off; for a new one follow the instructions included in the light fixture package.
With all switches, receptacles and light fixtures, turn the circuit back on and test them before securing the boxes or fixture in the wall or ceiling
These are fairly simple tasks. It takes a little more skill to install dimmer switches or such room light with multi-purposes like ceiling fans, but these devices comes with relatively detailed instructions that the handy homeowner should be able to handle.
Where it gets tricky to install such devices is when you are putting a light fixture on two switches, like at opposite ends of a hall, both of which can turn on and off the lights. These are called 3-way switches.
First, bring the power supply in to one of the switch boxes (one hot, and one neutral), on a #14/2-wire cable, then run a #14/3-wire to the other switch location. From the second switch, run a #14/2-wire up to the light box. In the first box, splice the neutral (white) wire from the power supply to the white wire in the 3-wire cable going to the other switch. Attach the hot (black) wire to the common screw on the 3-way switch. The red and the black conductor from the #14/3 cable will be called the “travelers”, and will hook up to the two remaining screws on the switch. At the other switch location, you will hook the white wire from the #14/3 to the white wire going up to the light. The “travelers” (black and red) from the #14/3 will connect to the same screws as on the other 3-way switch, and the black wire going to the light will tie on to the “common” screw.
Of course, if you are installing switches and plugs into kitchens, bathrooms, basements or garages, most local codes require these to be GFI – ground fault interrupter – switches; these are called for anywhere there is water in close proximity. These types of devices are wired similarly to regular devices, and the generally come with instructions that can be easily followed.
The thing to remember about electricity in the home, even on small projects, is that it can be dangerous. There is, of course, the potential of shock, and improper wiring can lead to fire. Some older homes, wired before current codes were in place even just a few short years ago, have wires that would not pass muster in today’s environment, and years-older homes contain wires that were never color-coded. The best rule of thumb is: if in doubt, call a professional.

Electrical Hazards of Weather
Posted at 5:00 pm by admin in electrical safety
High winds and severe weather can bring risks to home and commercial electrical systems
Downed power lines and the presence of water around electrical outlets and appliances are never good things, and a word to the wise is to call a professional if a risk appears likely
Throughout the summer there have been reports of severe flooding and other weather emergencies all across the country and while the Denver area has been spared from catastrophe heavy “monsoon” rains here in July have brought a little havoc to the area. A key issue in any weather situation, whether big or small, is to safeguard people and their homes from damage to electric power lines, electrical systems and appliances that often result from severe weather.
Among the first things reported in weather emergencies are power outages that obviously have an effect on lifestyle, but these can also be accompanied by dangerous situations of exposing people to electric shock and injury, and sometimes even cause fire. High winds associated with powerful storms often bring down power lines, lightning strikes can short out substations and even home electrical systems, and water from flooding or heavy rains is never a good thing when it mixes with electricity.
As residential and commercial electricians serving Colorado and the Denver area for a dozen years, Allstar Electrical Services has been called out scores of times for weather-related electrical damage repair or systems safety checks and advises that homeowners and business alike should taker extreme caution if they suspect an electrical compromise in or around their properties during or after a storm.
The first thing, obviously, is to stay away from downed power lines and call the local utility company. In some cases it is also wise to call 9-1-1 with the report of downed power lines so that emergency services can respond and protect people and property. If it involves power lines, the emergency responders will take care of calling in the utility line people for safeguarding and repair. Rain and standing water only exacerbates the situation and downed power lines should be addressed with extreme caution.
Another potential electrical safety problem area is flooding, and in our experience problems most often occur as a result of basement flooding. While there are going to be other problems associated with significant basement flooding, the first safety issue is to be very wary of standing in water that may have compromised electrical outlets, appliances and lamps, hot wate5r heaters, furnaces and the like. While up-to-date electric codes mandate the use of GFI (ground fault interrupter) outs, switches and circuits in basements (and anywhere else in proximity to water; e.g. kitchens and bathrooms), many older homes have not been updated with such equipment and may expose a homeowner to shock. The best advice: avoid standing water that could be exposed to electricity and call in a professional to handle the situation.
While basements are the most obvious locations for water damage in severe storms, such weather can also damage roofs, windows and doors. Once again, it is never a good thing if water mixes with electricity, so if you suspect water damage coming from the roof or broken openings, check the electrical first before marching in on a repair. Roof damage in particular could bring water into the walls, unseen, where electrical connections reside, so take caution turning on switches or appliances, unplugging things, etc. If there’s any doubt, call a professional electrician.
One of the most frequent electrical situations we encounter are blown circuits and damaged appliances as a result of power surges during electrical storms. The best way to protect your home and its electrical equipment from lightning damage is to unplug everything, however that it often impractical. Infrequent-use appliances — like toasters, blenders, hair dryers and curlers, etc. — should be unplugged when not in use anyway; even off they continue to drain power. Wired appliances like TVs/entertainment centers and computers should be connected with power-surge strips or other technology to protect them from “blowing up” as a result of a power surge or strike. Also, after an electrical storm it is best to check appliances, switches, receptacles and outlets for any obvious signs of stress – short circuits, excessive heat, smoldering – as these are signs that the electrical components have been compromised and may pose a risk of shock or fire.
And finally, a word to the wise: often after severe weather or a storm has knocked power out of a home, people turn to portable gas-powered generators to get some lights and some essential things working. Always operate a generator with full ventilation to avoid carbon monoxide poisoning, and never ope5rate them inside a basement, garage or inside the home.
The good news is that only under the most extreme weather conditions does modern electricity become compromised and pose a risk. For the most part, the home electrical is safe and will provide years of worry-free service if proper maintenance is conducted and upgrades are made at the appropriate times (e.g. new additions to the house, new and heavy energy consuming device like air conditioning). Just keep in mind that it is never wise to take a chance when there is a potential for an electrical hazard, like high winds and the presence of heavy rain or flooding near electrical devices. Call a professional and all will be safe.

Commercial Electrical Contractors Bring Specific Expertise Designed to Meet Business Needs
Posted at 4:07 pm by admin in Electrical Installation.Electrical Repair.Uncategorized
Hiring a commercial electrical contractor for new buildings, retrofit projects, and existing facility upgrades and maintenance will pay dividends to property owners seeking to get their projects done right, on time and on budget
DENVER, CO – Commercial and industrial property owners generally employ a maintenance supervisor to handle the routine repairs and fixes in office buildings, retail centers, warehouses, and manufacturing facilities, but when it comes to major repairs, upgrades and installations it is best to hire an experienced contractor with the specific expertise in the task at hand.
Nowhere is this more true than in a commercial property’s electrical system, as wiring, lighting and power needs of such facilities are subject to rigorous local codes and specifications, and only a licensed, bonded and insured electrical contractor can ensure the accuracy and speed necessary to keep business operations in the buildings running smoothly. Plus, an experienced commercial electrical contractor is specifically trained to keep utility costs in check, helping commercial property owners manage their power expenses in the most efficient manner possible.
The wiring, lighting and power usage in a commercial property is always unique to the situation at hand. Factors like the number of people working in the facility, the hours of operation, the types of businesses and their individual power usage, the number of visitors (like customers in retail), and special considerations for industrial machinery all come into play.
There are actually three specific instances where it pays dividends to call in a professional commercial electrical contractor.
First is on a design-build project, one that is the construction of a new facility from the ground up. Experienced commercial electrical contractors have broad experience working with architects and architectural plans and can assist with expertise in the overall design of the buildings’ electrical systems. This can include LEED certified buildings, as many electrical contractors have experience in meeting the often stringent demands of energy efficient buildings, with attention to detail on such issues as solar applications and LEED qualifying interior and outdoor light systems.
Another application for calling in a commercial electrical contractor is for a redesign or retrofit building project where often outdated existing electrical systems are completely overhauled to meet current codes and the new purposes for the building. Once again, working with architects and interior designers, an experience electrical contractor is fully versed in having retrofit properties meet the demand of the new uses.
And finally, electrical repairs, upgrades and maintenance on existing facilities in use by occupant businesses will ensure that the property meets the electrical demands of the tenants while at the same time keeping in mind that downtime for any business is a costly expense for the tenants and building owner alike.
Here’s a handy checklist of things to look for in a commercial industrial electrical contractor:
- Expertise. Make sure, through due diligence, that the contractor and each of its electricians have expertise in the type of project under consideration. For instance, if the building is a retail center, has this contractor done the same kind of work successfully on a similar, and similarly sized project? Any reputable commercial contractor will have references; check them.
- Licensure. Make sure the electrical contractor under consideration is fully licensed in the jurisdiction where the work is to be performed, and also check if any complaints have been filed against the contract5or and, if so, how they were resolved.
- Certification. There are a variety of certifications available to commercial electrical contractors, including those from trade associations and PSHA (The U.S. Occupational Safety and Health Administration). These certifications insure that the contractor and its licensed personnel have complete all the necessary continuing education to stay current in their field and the ensure workplace safety.
- Insurance and bonding. This is a very important step to protect against any mishaps or injuries on the job site. Ask for information about the policies and bonds in question to make certain they include the proper level of financial protection and building-owner indemnification. It’s a good idea to have an attorney check the policies to ensure they are up-to-date, cover the company and the individuals involved in the project and provide the proper coverage and protection.
- Outside sources. Vet the potential commercial electrical contractor with the local Better Business Bureau to check standing, complaints and resolutions. Also, many states and local government jurisdictions have boards and commissions that also collect and disseminate such information.
Commercial electrical work, from the complex to the very minor, is exacting and involves a whole host of business considerations. Getting the job done right, on time and on budget are essential to the property owner and the tenants of the facility. Commercial electrical contractors with the requisite experience are highly trained to deliver just what is needed and hiring the right one will pay dividends to commercial/industrial property owners for years to come.
In Denver and throughout Colorado, Allstar Electrical Services have been providing expert commercial/industrial electrical contracting to new and retrofit properties, as well as providing upgrades and maintenance services for commercial properties for over a decade. The company has worked with property owners, individual tenants, developers, architects, insurance companies and designers on everything from complete design-build projects, to such services as machine hookups, security systems, computer circuits, and much more.

With Home Electrical, Caution and Care Keep the Power Safe and Secure
Posted at 4:02 pm by admin in Electrical Installation.Remodeling.Safety
From minor electrical repairs to simple common sense about the use of electricity in a home, a few safety tips will keep homeowners in the electrical loop
DENVER, CO – The electrical service in any home is at the heart of family’s lifestyle, operating the lights, appliances, the air conditioner, even the hot tub. Everyone understands that, of course, but like everything else that just comes “on” with the flip of a switch, electricity is just one of those things we take for granted – until an emergency or the need arises.
As licensed and experienced electricians serving the Denver metro area for over a decade, Allstar Electrical Services works regularly with all kinds of clients: those who are informed, the misinformed and those who simply just want it fixed or expanded. In any case, when it comes to a home’s electrical service the admonition is for caution. Electricity can kill, injure or create fires if not handled properly, and it pays to know some basic safety rules.
The most basic safety and convenience rule is to know where the home’s electrical service box is located. Most often referred to as the circuit breaker, this is the usually grey box on the back of the house where the electrical service comes in from the utility. The box itself is designed to gather that electric service and then distribute it throughout the home through the many circuits on the box’s panel. These circuits come in different power ratings, like 20 amp or 15 amp, depending on the room or the appliance being served and the electric demand in question (e.g., kitchens typically need a higher power rating to handle the refrigerator and all of the other appliances, and often will be served by two or circuits). It’s good to know where this electrical panel/circuit breaker is in the event a circuit trips and power needs to be restored, and also so the homeowner knows where to turn off a circuit for minor repairs or the whole service in case of an emergency. Of course, we recommend keeping the area around the circuit breaker free of obstructions – patio furniture, plants, etc. – so there is easy access year round.
It’s also good to know how a particular home’s electrical panel is rated. For a long time, and until up to about 15 years ago, the basic standard was 100 amp service. But today most homes, even small ones, require (and may be mandated to have) 200 amp service at minimum. The reason is simple: home electrical demand has mushroomed, with entertainment systems, computers and accessories, and the myriad of electrical appliances and power chargers that have become part of everyday life in recent years. Think about; we used to have a television, and that has been overtaken by a whole system consisting of a TV, DVR, surround sound, DVD, game system, all often drawing power from the “plug” that used to power just the TV.
Knowing what’s there is important. A recent customer of ours, in an older Denver home, wanted to add a few new outlets in the home, add electrical service and lights to his garage, install a ceiling fan, and install a new chandelier. Easy, right? Turns out he had 100 amp service, inadequate (and out of code), that was already a safety hazard to the home, much less with increased demand. We upgraded the home to 200 amp service, fulfilled all of the increased electrical convenience in the home, and now he is poised to be able to add more conveniences (A hot tub? A swap cooler?) with ease. Also, it should be noted, it would have been impossible to sell this home without upgrading to 200 amp electrical service before placing the property on the market.
When performing relatively minor home electrical repair, like replacing light switches or wall outlets, here’s how to keep safe:
- Locate the proper circuit breaker in the circuit box and turn off the electric to the circuit to be worked on. Before commencing work make sure the circuit is off; plug in a lamp in the outlet or one nearby on the same circuit to make sure the circuit is off. If in doubt, don’t proceed. Use a voltage meter to check if the power is off.
- Study up and read the directions. Most electrical devices come with instructions, and it is wise to follow these to the letter. You want to make sure positive is positive, negative is negative, and the ground is installed properly. If the device purchased has scant directions, there are plenty of helpful sites on the internet to walk even the novice through a simple repair.
- Install the right switch/outlet. Bathrooms, kitchens, garages and any location where an outlet or a device plugged into it may come in contact with water require a GFI (ground fault interrupter) that protects against shock. Not only is it wise, it is code in most areas.
- Use tools – screwdrivers and pliers – with rubber/insulated grips or handles. Probably wise to wear gloves, too.
- Never stand in water while attempting an electrical repair.
- Wear shoes with non-conductive soles, like tennis shoes. Also, wear protective eyewear.
- Red and black wires are typically the “hot” wires, meaning the current is flowing from the circuit breaker. White wires are usually the negative or “return” wires, and the ground wire is generally bare. Older homes, however, may feature wires that are not color-coded. In this case you can use a voltage meter (you’ll have to flip the circuit break back on once the wires are exposed) to check.
Many people also attempt, with varying degrees of success, to do more complicated jobs like installing a ceiling fan or putting in a new outlet or switch themselves. Ceiling fans, particularly those with lights as well, are complicated, and we get a ton of calls to finish up where the homeowner failed. Our advice: read the directions closely, and then again, build the fan on the floor first, and make sure you fully understand the wiring. Also, beyond wiring, make sure the anchoring bracket can handle the job and that the fan is installed properly on the bracket; a fan creates momentum and can easily throw itself off an unsecure bracket, creating a myriad of problems.
Additional light switches and/or outlets require cutting into the wall, locating the feed wires and tapping them, and perhaps pulling additional wire. Study up because there are code requirements about distance off the floor, what kind of wire to use, etc. And often such a job requires a permit to be pulled from the local government jurisdiction and a demonstration that the installer knows more than the basics about such an installation.
For these things, the Allstar Electrical Services recommendation is to call in a professional, licensed electrician so there will be confidence in the outcome.
Here are a few other, more basic electrical safety tips:
- Extension cords are meant to be temporary, not a component of the house wiring. They tend to heat up over time and should never, ever be placed under carpets, rugs or furniture. Never staple an electrical cord into place to keep it off the floor; should the need arise, there are U brackets which don’t pierce the cord for this purpose.
- Don’t overload circuits. If you experience tripping circuit breakers frequently when turning on multiple appliances (e.g. the microwave and the toaster), that circuit is underpowered or you need an additional circuit in that area.
- Power surge extension cords may protect the device plugged in from a power surge, but remember that if you plug multiple devices into the surge protector (e.g. computer, printer, keyboard) they are all still being plugged into a single outlet. Not recommended.
- Keep portable heaters and space heaters well ventilated and away from things that can burn, like carpets, furniture, newspapers/magazines and the like. And never operate them if no one is around.
- Unplug appliances – and, yes, charger cords – when not in use. Not only is it a potential electrical hazard, even a toaster plugged in but not in use is drawing power and wasting energy.
Electricity is, of course, a wonderful commodity that fulfills our lives in big and small ways each and every day. But it is also potentially dangerous and should be handled with care. With a growing demand for electrical devices in every room of the house, keep in mind that most Americans are continually adding to the strain on a home’s electrical system, and like anything else it should be inspected by a professional periodically to make sure it is in tip-top shape. Second best just won’t do.
Except for the most minor repairs, it is not recommended that homeowners perform electrical work. It is dangerous, of course, but also there are a ton of rules and regulations that must be followed that only professionals keep fully abreast of. We at Allstar Electrical Services perform the full gamut of home electrical tasks, from the minor to the very complex, including inspections, to ensure everything is in order. Phone us at 303-399-7420 for complete details on any electrical project.
