Michael from Middletown, NJ has been a Green Sun Energy Services client since November of 2021. A Generac Guardian rated 22 kW on propane and 19.5 kW on natural gas went in the following April, running on natural gas behind a 200-amp automatic transfer switch. The load survey put 3,684 square feet of living space behind it, which is what puts the machine at the top of the air-cooled range, and the switch is sized to the service so the whole house comes back rather than a chosen part of it.

Standby generator questions from Middletown 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.
Does new gas piping have to be pressure tested in Middletown?
Yes. Gas piping subject to the adopted fuel-gas code must be inspected and tested before it is accepted. New Jersey adopts the 2024 International Fuel Gas Code, which governs the inspection, the test pressure and how long the test has to hold.
What happens if we add a heat pump, a pool or an EV charger later?
Any major new electrical load should prompt a review of the generator's capacity. A machine sized correctly at installation may no longer be adequate once substantial loads are added. Load management can often accommodate the new equipment without replacing the generator.
