Joseph from Manchester, NJ has been a Green Sun Energy Services client since January of 2024. The machine is a Generac 7226 rated 18 kW on propane and 17 kW on natural gas, running on natural gas, on a 150-amp transfer switch, and it was commissioned in March of 2024. The house is about 1,675 square feet, which is well inside what 18 kW carries – the size follows the equipment that has to start, not the floor area. Green Sun has serviced it in February of 2025 and January of 2026, and it now reports to remote monitoring in between.

Standby generator questions from Manchester homeowners
Does new gas piping have to be pressure tested in Manchester?
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.
How is a standby generator grounded?
The grounding and bonding arrangement depends on the transfer-switch configuration, and in particular on whether the neutral is switched and the generator therefore treated as a separately derived system. It is designed by a qualified electrical contractor rather than assumed from another installation.
