Mark from Roosevelt, NJ has been a Green Sun Energy Services client since November of 2025. He signed in mid November and the generator was commissioned in the first week of January, an 18 kW Generac on a composite pad behind a 200-amp service-rated transfer switch, with surge protection and a load management module. It carries 2,619 square feet with two refrigerators, a freezer, a dishwasher and the laundry. Roosevelt is in Monmouth County, one of the smallest boroughs we work in.

Standby generator questions from Roosevelt homeowners
Does the residential building code apply to a generator?
It can. For applicable one- and two-family dwellings New Jersey adopts the 2024 International Residential Code, subject to state amendments. Structural and flood-related generator installations may therefore need review under the residential subcode as well as the electrical and fuel requirements.
How quickly does it take over?
The automatic start sequence normally begins within seconds of the controller deciding that utility power has failed or fallen outside acceptable limits. There is a deliberate short delay so that a momentary flicker does not trigger a full start and transfer. Exact timing depends on the controller, the transfer switch and the configuration.
Can the existing natural-gas service in a Roosevelt home supply a generator?
Often yes, but the gas system has to be evaluated first. The review covers the generator's BTU demand, meter capacity, available pressure, regulator capacity, pipe diameter and length, and every other gas appliance in the house -- furnace, boiler, water heater, range and fireplace among them.
