Most whole-house standby generator projects in this area run in the mid-four to low-five figures installed, driven mainly by unit size, transfer switch type, and distance from the panel and gas line. We give you a fixed written number before anything is ordered.

Generator Installation questions

How long does a standby generator installation take?
Most residential installations are completed in one to two days on site once the unit and permit are in hand. Utility or propane supplier scheduling is usually the longest lead item.
What size generator do I need for my house?
It depends on whether you want whole-house coverage or essential circuits only. A typical New Hampshire home with well, heat, and kitchen runs 18–26 kW for full coverage. We calculate it from your actual panel and loads.
Do I need a permit for a generator in New Hampshire?
Yes. Standby generator installations require an electrical permit and inspection, and often a gas permit. Copp Electric files the paperwork and meets the inspector as part of the job.
Can a generator run on propane?
Yes. Most homes in the Franklin area run standby generators on propane, and many units can be configured for natural gas where it is available. We coordinate the hookup with your fuel supplier.
