Daniel from Springfield, NJ has been a Green Sun Energy Services client since August of 2021. The generator was commissioned that October: 14 kW on natural gas, on a 200-amp service-entrance switch with a smart management module, sized against a 13 kW calculation for the 1,528 square foot house. One condition was set out before the contract was signed: the Verizon FIOS box had to be moved to the right of the electric meter before installation day. Clearances around a meter and a transfer switch are set by code rather than by preference, and an inspector will fail work that does not have them – so the box comes first, whatever else is waiting. Two sump pumps and two refrigerators make up most of the load, and annual maintenance, an extended parts-and-labor warranty and monitoring we manage all sit behind the machine.

Standby generator questions from Springfield homeowners
Does new gas piping have to be pressure tested in Springfield?
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 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.
How quickly does it take over?
The automatic start sequence normally begins within seconds of the controller deciding that utility power has failed or fallen outside acceptable limits. There is a deliberate short delay so that a momentary flicker does not trigger a full start and transfer. Exact timing depends on the controller, the transfer switch and the configuration.
