Commercial Generators

What is a power generator?

A backup power generator independently provides a backup source of power in the event of a power outage. Similar to an automobile, a generator creates mechanical energy with the help of a heavy-duty recharging battery to initiate and maintain energy, a fuel tank to supply fuel (gasoline, diesel, or natural gas), an engine, and an alternator to convert that mechanical power into electrical power.

Generators are useful for your business:

Power generators ensure continued productivity in the event of a power outage, keeping necessary appliances in operation.

A power generator ensures the safety and comfort of your employees during the event of a snow storm, ice storm, or heat wave.

A power generator protects computer data and allows security systems to continue to function.

Automatic Standby generators provide an uninterrupted supply of power, despite brownouts and outages, keeping all devices running like normal.

Types of Commercial Power Generators


Portable generators may be wired into a subpanel by an electrician or simply plugged into appliances using extension cords. They power only chosen essentials such as lights, refrigerators and some computers. They are a simple and inexpensive backup power option, but must be started and maintained. They offer a limited supply of electricity, providing enough power for two to four outlets or a few specific circuits when wired in. These generators must be located at least 10 feet away from your business, away from doors and windows, and in a completely open area (not even carports or awnings are safe) to avoid carbon monoxide poisoning.

Automatic Standby

Automatic standby generators start automatically during power outages, preventing interruptions in electrical service. They are powered by natural gas, propane and/or diesel, are quieter than portable models, and have the ability to power everything in your business. They come at a higher price than ones used in the home, and also require the professional installation of a transfer switch, a subpanel, and the power generator itself.

Professional Generator Installation Chattanooga

A professional can determine the right size generator for your needs.

Do you know how to properly calculate wattage so that your system isn't overloaded at startup? This varies depending on the equipment you need to power and the manufacturer of your generator. Our professionals have the skills necessary to calculate power needs for a smooth operation.

Professional installation ensures safety.

A professional electrician can safely set up wiring, plugging your generator into the transfer switch and wiring it directly to your business's service panel. This disconnects you properly from the grid and ensures the safe delivery of power only to designated circuits, preventing the overloading of you generator, backfeeding, fire, and other safety issues. Proper positioning and installation of your portable generator is also essential in preventing carbon monoxide poisoning.
