Michael from West Long Branch, NJ has been a Green Sun Energy Services client since December of 2020. The generator was commissioned in September of 2021: 17 kW on natural gas, on a 150-amp managed whole-house switch with two smart management modules, sized against a 14 kW calculation for the 1,900 square foot house. Two sump pumps are the load that decides the case here – a house with one has a wet basement, a house with two has already learned that one is not enough, and both will be running in the storm that takes the power out. A refrigerator, a washer, a gas dryer and a dishwasher complete the list. Nine months separated the contract from the commissioning, which was the shape of generator work through that period.

Standby generator questions from West Long Branch homeowners
Will a 22 kW generator run an entire West Long Branch 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.
Can the generator stay connected during a pressure test?
The machine has to be protected from test pressures beyond what its fuel controls are built to withstand. The fuel-gas code sets out when appliances are disconnected or isolated for testing, and the plumbing contractor follows both that code and the generator's installation instructions.
What is a service-entrance-rated transfer switch?
One that is listed for use as service equipment when installed in the appropriate configuration. These are commonly used for whole-house systems, where the transfer switch becomes part of the home's service arrangement rather than sitting downstream of it.
