Generator Installation in Delafield, WI
A Wisconsin outage in January is not an inconvenience, it is a frozen-pipe risk. A standby generator installation in Delafield keeps the furnace, sump pump, well pump and refrigerator running automatically, whether you are home or not.

The generator itself is only part of the job. Sizing comes first: we add up the loads you want to run and choose a unit that can start them without strain. Then comes the pad and placement, the gas connection in coordination with your plumber or gas supplier, the automatic transfer switch at the panel and the permit. Generac is headquartered right here in Waukesha, Wisconsin, and its air-cooled home standby units are the ones we are asked about most, but we install and wire other major brands as well.
Delafield sits in the most densely built corner of Wisconsin, where housing runs from pre-war bungalows and duplexes to new subdivisions. Older homes around Waukesha County often still have 60 or 100 amp services, cloth-insulated wiring and too few outlets, while newer ones are adding EV chargers and finished basements. We work on both every week.

Delafield generator installation FAQ
What size generator do I need for my Delafield home?
It depends on what you want to keep running. Many homes with gas heat are well served by a 14 to 26 kW air-cooled unit. We do a load calculation rather than guess, because an undersized generator stalls and an oversized one wastes fuel.
Does a standby generator run on natural gas or propane?
Either. In town, natural gas is the usual choice. Rural properties around Delafield typically use propane, and we coordinate tank sizing with your supplier.
How long does installation take?
The on-site work is usually one to two days once the generator, permit and gas connection are lined up.
Can I just plug a portable generator into an outlet?
No. Back-feeding through an outlet can electrocute utility workers and destroy your generator when the grid returns. An inlet box with an interlock or transfer switch is the safe, legal way to do it.
