FAQs
Is a permit required for a commercial generator in Aiken?
Yes. Both Aiken County and the City of Aiken require permits for electrical and fuel work. Only licensed electricians can perform the installation.
How long does a 26kW install take?
Simple projects can take about a week. More complex jobs with trenching, panel upgrades, or 3-phase service may take several weeks.
Do I need a 3-phase generator?
If your building has 3-phase service, you may need a generator and transfer switch designed for 3-phase loads.
Will 26kW run my whole business?
Often, no, it is usually sized to run critical loads only. A load calculation will confirm coverage.
Natural gas or propane?
Both work well. Natural gas offers convenience if available, while propane is a good alternative where gas service isn’t. Regardless of the fuel source, gas piping must be done by a licensed plumber.
What about noise and placement?
Generators must meet local noise ordinances and clearance requirements. A proper pad and strategic placement help minimize impact.
