Charles from Lawrenceville, NJ has been a Green Sun Energy Services client since March of 2023. The generator was commissioned in June, sized against a 20 kW calculation for the 4,600 square foot house, with two sump pumps, an electric oven, two refrigerators and a separate freezer on the load list. One condition was agreed before the work: a tree stump had to be ground out and the ground levelled where the generator would sit. A generator needs a flat, stable base that will still be flat in ten years, and a rotting stump underneath is not that – it is the sort of groundwork better settled in the contract than discovered on installation day. Annual maintenance, a ten-year extended parts-and-labor warranty and monitoring we manage all sit behind the machine.

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.
Which fuel-gas code applies?
New Jersey currently adopts the 2024 International Fuel Gas Code as its Fuel Gas Subcode, which is what governs the piping, testing and shutoff arrangements on a natural-gas generator installation.
Will a 22 kW generator run an entire Lawrenceville house?
For many homes, yes, but that does not mean every load can run at the same moment. Houses with two central air conditioners, electric heat, EV charging, pool equipment or electric cooking may need load management or a larger machine. The answer comes from a load calculation rather than from the phrase whole house.
