Ashish from East Brunswick, NJ has been a Green Sun Energy Services client since March of 2025. The Generac 6250 at the house is rated 20 kW on propane and 18 kW on natural gas, runs on natural gas, and feeds a 90-amp transfer switch. It was installed in January of 2014 by another company, and Green Sun serviced it in April of 2025. On a machine past its eleventh year the first visit is a longer one than the annual that follows – it is where the gas pressure, the switch and the exercise settings get checked against what the manufacturer asks for rather than assumed.

Standby generator questions from East Brunswick homeowners
Does new gas piping have to be pressure tested in East Brunswick?
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.
What does a whole-house generator actually mean?
Whole-house generally means the transfer equipment serves the home's main electrical system rather than a small emergency-circuit panel. It does not promise unlimited capacity. High-demand appliances may still be prioritized or briefly shed while generator capacity is being used elsewhere.
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.
