  • Transfer Switches

    Having your transfer switches safely installed by an AEI electrician gives you the peace of mind that the work has been properly completed. Transfer switches are a required component of having a generator installed for the purposes of providing your business with the power it needs to operate at optimal performance.

    Connected to both your utility power and your commercial-sized generator, a transfer switch is needed to provide power to your business during power outages, including brown outs and black outs. As such, it is an important component of your generator, isolating each power source to prevent back-feeding, while also enabling a power source for your operational needs. If back-feeding occurs, it could lead to a dangerous power feed, resulting in injury or death to anyone working on utility power lines.

     

    Types of Transfer Switches

    Three basic types of transfer switches are available for commercial business use. They include automatic switches, manual switches, and combination (manual/automatic) switches.

    • Automatic transfer switches provide the unique advantage of transferring the power source automatically between utility power and generator power.

    • Manual transfer switches offer the flexibility of allowing you the option of turning the switch on and off at your discretion.

    • With a combination (manual/automatic) switch, you gain the advantage of both options, making it easy to maintain power to critical pieces of equipment.

     

    Transfer Switch Sizes

    The size of your transfer switch is contingent upon several different factors. They include each of the following aspects of your commercial business:

    • The size of the utility service you use
    • The size of the generator you have installed
    • The number and type of appliances you plan to operate

    Transfer switches are sold in a variety of styles. Your AEI commercial electrical team can assist you in choosing the correct style for your business requirements. Please contact us today to discuss your choice of transfer switch and to schedule an appointment to install one.

  • Security Lighting Installation

    While solar lighting may be inexpensive, it does not provide the level of security that you need for your home. Moreover, the light they provide is reliant on sunny days, limiting the availability of your source of illumination. Instead of trusting that such unreliable sources of security lighting can protect your home from invasion while offering a safe path to the home from your car during the evening/nighttime hours, you may want to consider having security lighting installed by a professional. In addition to hardwired fixtures with a constant on-or-off feature connected to an electrical source, you can include those designs set up as motion-sensor lights, providing the best of both worlds to your safety plan.

     

    Considering Security Lighting Installation Purposes

    In general, the primary goal is to situate security lighting in locations where they will startle intruders, either scaring them away or giving you enough time to react to their unwanted presence. Improperly placed security lighting invites criminals to your home or business, delivering a clear view of your building. This is one of the reasons why today’s security lighting options no longer include only bright globe lights and huge flood lights. Today, motion-sensor security lighting options are available along with subtle light styling that helps protect your building from invasion.

     

    Strategically Placing Security Lighting Fixtures Outside Your Home or Business

    The main component of properly installing security lighting is to locate it in an optimal spot so that it delivers the best advantage for creating a safe environment. Our licensed electricians are knowledgeable about the installation of security lighting and can help you determine the best strategy for your situation.

     

    General Tips for Strategic Security Lighting Placement

    Security lighting should be placed in locations that are appealing to intruders – the darkest entrances to your home including doors, windows, and gates.

    When installing motion-sensor security lighting, be sure to obtain newer models designed to turn on only when people or larger animals enter the area.

    Shrubs and bushes obscure the area where they are located, so security lighting should be located nearby.

    Flood lights are great deterrents to intruders and cover a large area, making them quite useful for backyard coverage.

    A junction box dedicated specifically to your security lighting, providing you with a single location for troubleshooting in the future when necessary.

  • Recessed Lighting

    Recessed lighting solutions for commercial buildings are available in a wide assortment of styles that offer energy efficiency and high performance. Of course, three basic types of recessed lighting are sold today – standard voltage, low voltage, and solar.

    Standard voltage -  offers a simple design that requires little maintenance once it has been installed. All you ever need to do is replace the light bulb when it no longer works. This is the most popular style of recessed lighting available today. Standard voltage fixtures are sold in a varied assortment of sizes, so they can be used in almost any location within your commercial building.

    Low voltage fixtures  only use a range of 12 to 24 volts. Therefore, their installation includes a transformer that reduces the standard voltage of 120 volts found currently produced by most electrical setups. Low voltage recessed lighting is also popular, particularly because of the wide selection of styles that are currently being sold. However, while the installation costs are only slightly more expensive that those incurred with standard voltage installations, the cost to maintain and repair this style is expensive.

    Solar recessed lighting  fixtures have the most difficult and costly installation process. A hole must be cut into the roof of your commercial building in order to place the required reflector globe that contains the reflective tubes that create your source of light. While you might save money on your lighting costs, this style of recessed lighting can only function when the sun is out.

     

    Recessed Can Lighting

    Offering a clean appearance for the lighting system in your place of work, recessed can lighting fixtures are fitted flush into the ceilings. Unlike the earlier versions of can lighting, newer styles offer greater efficiency. The seals used when installing them create an air-tight design that prevents heated/cooled air from leaking out of the room into the attic.

     

    Insulation Contact Ratings for Recessed Lighting

    In order to avoid a fire hazard, recessed lighting fixtures have an IC (Insulation Contact) rating that lets you know they do not pose any hazard related to the heat they emit. The IC rating lets the electrician know that the fixture can be installed safely into the ceiling. Some styles even come with thermal switches designed to reset the lighting fixture under certain circumstances.

  • Parking Lot Lighting

    Commercial Parking Lot Lighting

    An essential aspect in your business, the lights in your parking lot play a multi-functional role. They should provide sufficient illumination for anyone entering or leaving your parking lot during the evening and/or nighttime hours. Moreover, their presence should protect your customers from unnecessary danger, such as tripping over something on the ground.

    Your goal should be to create a pleasing light pattern that draws customers to notice your building. Of course, you’ll also want to obtain cost-effective lighting fixtures in order to limit your company’s overhead costs. You have many options from which to choose, including standard poles, decorative fixtures, and streamlined styles. We can recommend the best and most cost efficient option for your application

     

    Standard Parking Lot Lighting

    The standard lamp version for parking lots lights offers a high pressure sodium lamp or a metal halide lamp. Both of these solutions feature ballasts that must be mounted either directly behind the lamp or right above it. Today’s styles feature compact luminaires with attractive styling and high performance.

  • Power Transformers

    Commercial Power Transformers

    Accommodating the electrical loads needed by your commercial building is readily accomplished when you select the right size and type of power transformer. This fundamental piece of equipment is an essential aspect of your power distribution needs. It delivers the voltage levels required to produce the electrical loads needed throughout your building to keep your equipment running properly.

    The installation of your commercial power transformer must comply with NEC (National Electrical Codes) as well as any local or stated ordinances that apply. Contracting an AEI  electrician to complete the installation for your place of business ensures that the work will comply with all codes

    An indoor distribution transformer is mounted separately from the panel board. In some cases, the transformer must be installed in a special vault room that has been designed with fire-rated enclosures. Pad-mounted transformers require outside installation. Therefore, they are weatherproof and tamper resistant.

    Types of Commercial Transformers

    It is important to understand the differences among the various styles of commercial transformers to ensure that the one installed can meet your company’s needs. Here is a look at several types:

    Cast-coil transformers – Using reinforced resin to encapsulate the windings of the transformer, this style is useful in locations where airborne pollutants and/or moisture exist.

    Oil-filled transformers – Featuring an oil-filled tank containing insulating mineral oil that is used to encase the windings, this style requires high maintenance in order to sustain its usability.

    Ventilated dry-type transformers – Designed with a variety of insulating materials, the ventilated dry-type requires a large clearance space and is ventilated by air. An enclosure protects the windings from damage, while also acting as a safety measure. They are available in a variety of sizes and dimensions.

    Non-ventilated dry-type transformer – Featuring total enclosure, this style is perfect for use in commercial areas where excessive corrosion and dirt exist.

    Sealed dry-type transformers – Offering the flexibility of being installed either indoors or outdoors, this style contains an enclosed tank filled with nitrogen or another type of dielectric gas that has been included for the protection of the windings. This style is particularly useful for commercial businesses that use corrosive materials.

    Our electricians are licensed and experienced in every type of commercial electrical work. Please contact us to discuss your company’s need for a power transformer installation.

  • Generator Installation /
    Maintenance

    Are you worried about a loss of power that can shut down your business operations in minutes, leaving your employees floundering with nothing to do? Have you considered the benefit of having a commercial generator installed to avoid this type of circumstance?

     

    What Is a Commercial Generator?

    Designed as a standby device that kicks in during a power outage, a commercial generator supplies your business with electricity in order to keep your facility operating as normally as possible. A generator intended for commercial use is larger, so it has the capacity to provide a sufficient source for all of your essential electrical needs.

    In order to streamline the transition from normal operating power to backup energy, your generator is designed to switch on automatically whenever a sustained loss in electrical power is detected.  A properly installed commercial generator properly will do  the rest for you.

     

    What Essential Electrical Needs Can a Commercial Generators Fulfill?

    Your commercial generator will provide enough power for you to operate each of the following types of devices during the power outage:
    • Telephones
    • Lighting
    • Heating systems
    • Cooling systems
    • Computers and accompanying peripherals

     

    How to Choose a Commercial Generator?

    Your first decision is to select the type of fuel that you will use to run your commercial generator. You can choose a variety of fuels, including propane, natural gas, diesel, gasoline, and oil. Your choice should be based on the method that offers greater convenience, depending on your situation. For example, you might want to select a fuel  more readily available to your company.

    While some models are less expensive than other styles, the type of fuel needed to run them might not be as convenient to find. Moreover, you should also consider the tank capacity and how frequently it needs to be filled.

    Your selection of a commercial generator should also be based upon the output that your business needs to continue operating during the power outage. Our technicians can assist you in determining whether you need a model with an output of 25 kilowatts, more than 1,000 kilowatts, or something in between those two capacities.

     

    Commercial Generators and Transfer Switches

    It is important to understand that your standby power supply requires a transfer switch to protect it against dangerous activity. The transfer switch prevents voltage from the utility company from entering and damaging your generator when the power comes back on. It also prevents dangerous feeding of power from your generator into the utility power lines.

    Our electrical technicians can install either a manual or an automatic transfer switch to protect your company against unusual transfers of power. Your switch must be rated to handle the largest of the following two aspects of your power supply: your company’s maximum load or the commercial generator’s full output.

  • Emergency / Exit Lighting

    Commercial

    In order to provide safety for the employees and visitors of any commercial building, emergency exit lighting is mandated by the locale in which it is located. Moreover, additions and construction that remodels an existing floor-plan layout often necessitates a change in the location of emergency egress lighting. If you have concerns about the existing emergency exit lighting that you have installed or you are in need of a new installation, please contact us to arrange for one of our licensed electricians to come out and handle it for your business.

    Regulations and Codes

    Our licensed commercial electricians are knowledgeable of any local codes and regulations regarding emergency exit lighting in each of the communities they service. Moreover, as responsible tradesmen, they are also fully cognizant of the requirements put forth by OSHA (Occupational Safety and Health Administration).  OSHA promotes safe practices deemed necessary to protect employees who are working on the job.

    Requirements

    According to the National Fire Protection Association (NFPA) and OSHA, a business owner must provide safe means of egress. They offer a clear portrayal of each of the following terms

    • Exit access – the area that leads up to the beginning of the exit

    • Exit – the area that provides a safe method of leaving (exiting) the building

    • Exit discharge – the area that fills in the space between the end of the exit and the beginning of a public area

    Each of these terms is important because OSHA has clear specifications for properly lighting the exit area of any commercial building. In particular, the exit route needs to offer sufficient lighting to enable an individual to be able to see clearly, given that he has normal lighting. Moreover, a clearly visible sign labeled with the word “EXIT” must be poised in such a way that it indicates the exact location of the egress.

    The NFPA also requires specific methods that must be used to properly illuminate the egress area. Each of the following terms identifies the type of lighting that a commercial business owner must provide for emergency exits.

    * Internal illumination – a light source must be set up inside the commercial building so that the exit access is   properly illuminated for visibility.

    * External illumination – a light source must be installed in order to provide a source of light that properly illuminates the exterior of the emergency exit for visibility.

    Additionally, the light sources must be independent of external power sources so that they continue to function in the event of a power failure.

  • Electrical Inspections

     

    Electrical Code Violations

    Whether you purchased a building with electrical code violations that you were unaware of or you hired an electrician who cut corners, correcting those code violations is essential for your business. Whenever a building undergoes an inspection, a risk always exists that the inspector will discover one or more violations related to your electrical wiring, outlets, switches, and circuitry. In some cases, the violations are due to an oversight on the part of the original electrician, and in other instances, the problems are the result of years of neglect and improper maintenance, leading to faulty, broken, or decaying equipment.

    Once an inspector identifies the code violations, an order that dictates the corrections that must be made is issued to the building owner. Fortunately, most electrical code violations can be remedied rather quickly due to the exceptional skills of professionally trained and licensed electricians. Approaching the matter in a timely fashion can help you to avoid additional fines, potential fires, and electrical shocks that injure your personnel.

     

    Problems Associated with Electrical Code Violations

    If a building inspection reveals electrical code violations, the business owner is subjected to fines as well as being required to arrange for all violations to be corrected within a specified timeframe. Not only can this process be expensive, but it can also lead to downtime for your business operations as well as unnecessary stress.

     

    Not only do you place your business at risk, but you also endanger the safety of your employees. As you can see, in addition to being a legal issue, it is also an ethical one.

     

    How Are Electrical Code Violations Determined?

    The standard by which all electrical wiring work must be completed is determined by the National Fire Protection Association (NFPA), which has compiled all of the codes into a book known as the NEC or National Electrical Code. AEI’s licensed electricians are qualified to complete the majority of work related to electrical wiring projects. A permit must be obtained and the work must be completed according to exact specifications.

     

    Common Electrical Code Violations

    A number of electrical codes occur more frequently than other types of problems. They include:

    • Lack of GFCI protection
    • Insufficient quantity of outlets
    • Improper wiring
    • Improper breaker sizes on circuits
    • Faulty circuitry
    • Improperly identified circuits on the panel
    • Overloaded circuits
    • Overloaded outlets
    • Faulty emergency/exit lighting
    • Non-functioning emergency/exit lighting
    • Improperly grounded metal boxes
    • Faulty wirings
