Fredric from Scotch Plains, NJ has been a Green Sun Energy Services client since August of 2019. The generator was commissioned that December: 18 kW on natural gas, on a 150-amp managed whole-house switch with two smart management modules, sized against a 15 kW calculation for the 2,600 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. Two refrigerators, a washer, a gas dryer and a dishwasher complete the list. Annual maintenance, an extended parts-and-labor warranty and monitoring we manage all sit behind the machine.

Standby generator questions from Scotch Plains homeowners
Does new gas piping have to be pressure tested in Scotch Plains?
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 can a whole house be carried on a smaller electrical service?
Through load management. One or more large loads are controlled so they do not start at the same moment, or shut down briefly if generator demand climbs too high. That is what allows whole-house coverage where the raw sum of every connected load would otherwise exceed the machine.
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.
