Ralph from Scotch Plains, NJ has been a Green Sun Energy Services client since November of 2023. The work was deliberately held until the following spring at the household’s request, and the generator was commissioned in April of 2024, sized against an 18 kW calculation for the 3,000 square foot house. Before it could begin, a holly bush had to come out and the area around the meter cleared. Booking in November for an April start is a sensible way to buy a generator: the survey, the permit and the utility work all take time regardless, and doing them across a quiet winter means the installation itself lands on a chosen date rather than an urgent one. A sump pump, an electric oven, two refrigerators, a washer and a gas dryer make up the load.

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.
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.
What is the difference between essential circuits and whole-house backup?
An essential-circuits system transfers a defined set of circuits through a smaller transfer switch rather than the whole electrical service. It is a deliberate design rather than a lesser one: the circuits that matter during an outage are chosen in advance, and the generator only ever has to carry those.
