Eitan and Jodi from Springfield, NJ have been Green Sun Energy Services clients since October of 2021. A Generac Guardian rated 22 kW on propane and 19.5 kW on natural gas went in the following March, running on natural gas behind a 200-amp automatic transfer switch. The load survey put 1,900 square feet of living space behind it – a generous machine for the floor area, and the switch is sized to the whole service, so the house carries on as normal rather than on a chosen handful of circuits.

Standby generator questions from Springfield homeowners
Does a standby generator need a permit in Springfield?
A permanently installed generator normally requires New Jersey Uniform Construction Code permits, because it involves permanent electrical and fuel work. Depending on the property and the municipality, building, zoning, floodplain, utility or fire-code review can also apply.
How level does a generator have to be?
Within the leveling tolerance specified in its installation manual -- applicable air-cooled instructions have used roughly a half-inch overall. A poorly prepared base can settle after installation and bring on drainage, vibration or enclosure problems that were not there on the day it went in.
Is an emergency shutdown required?
The 2023 National Electrical Code contains requirements addressing emergency shutdown of generator prime movers. Whether and how they apply is determined from the generator's rating, its location, the model and the installation, and the factory equipment is evaluated against them rather than presumed to comply.
