Arnold from Lawrenceville, NJ has been a Green Sun Energy Services client since October of 2020. The machine is a Generac 7043-2 rated 22 kW on propane and 19.5 kW on natural gas, running on natural gas, on a 200-amp transfer switch, and it was commissioned in July of 2021. At about 2,700 square feet with the whole panel transferring, nothing here is left off a list. Green Sun has serviced it every year since – July of 2022, June of 2023, June of 2024, May of 2025 and April of 2026 – and it reports to remote monitoring in between.

Standby generator questions from Lawrenceville homeowners
Does new gas piping have to be pressure tested in Lawrenceville?
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.
How much clearance is needed above a generator?
Applicable air-cooled guidance requires roughly five feet of overhead clearance from structures, overhangs and projections. That is what rules out a good many low decks, roof overhangs and alcoves as generator locations, and it is worth establishing early rather than after a site is chosen.
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.
