Commercial Generator Installation Services
Commercial generator installation gives a building its own power source for the hours the utility feed is down. The Generator Guys install commercial backup generators for owners who lose money the moment the lights go out. Our electricians are licensed under EC13005590. What an outage costs depends on what is inside. A restaurant watches a walk-in cooler climb out of safe temperature. A dental office stops mid procedure. A self storage property loses gate access and cameras. A small office loses the server closet and everything running on it.
A commercial power generator runs on natural gas, propane, or diesel. It sits on a pad outside the building, wired into your electrical service, and carries that load until utility power returns.
Sizing a Commercial Backup Generator Against What the Building Actually Draws
Commercial backup generator installation starts with a load calculation, not a catalog. We walk the building and add up what really pulls power: refrigeration, HVAC, compressors, lighting, elevators, and the equipment that brings in revenue. That total sets the kW rating.
Your service decides the rest. Three phase service needs a three phase commercial electric generator, and the voltage has to match what your panel and motors expect. Fuel is the next call. Natural gas runs off the meter with nothing to refill, though the gas line often needs upsizing for the BTU draw. Propane and diesel need onsite storage and a runtime plan.
Then the site work: a concrete pad, clearance from windows and air intakes, a sound rated enclosure near occupied space, and the [transfer switch] that ties the unit into your panel.
Commercial Standby Generator Installation, From Site Survey to Cutover
It starts with a site survey. We look at where the unit can sit, how far that is from your electrical service, whether the gas meter can carry the BTU draw, and what code clearances allow near windows, doors, and fresh air intakes. Then permits and drawings. Commercial work gets reviewed, and the plan set has to show the pad, the conduit run, the fuel line, and the tie-in point.
Install day covers the pad, the feeder run, the fuel connection, and the tie-in at your panel or switchgear. Commissioning comes last. We start the unit, cut utility power on purpose, and load test the building before signing off. The cutover is short, and we schedule it around your hours.
Tell Us What Cannot Go Down and We Will Size Your Commercial Generator Installation
Three details get you a real number instead of a range: the amperage and phase at your service entrance, the equipment that has to keep running, and whether you have gas at the meter or room for a fuel tank.
Fill out the form or call us. You will get a kW size, a fuel recommendation, what the install involves on your property, how long power is off during the cutover, and a timeline that accounts for permitting and equipment lead time. If a smaller unit covering only essential circuits does the job for less, we will say so instead of quoting you the bigger one.
