Chris from Farmingdale, NJ has been a Green Sun Energy Services client since August of 2019. The generator was commissioned that October: 20 kW on natural gas, on a 200-amp service-entrance switch with a smart management module. The load survey is one of the heaviest we have written up – two well pumps, a sump pump, two double electric ovens, two refrigerators, a washer and a gas dryer across 4,500 square feet, adding up to a 28 kW calculation. That is well above the machine that was fitted, which is exactly what load management exists for: rather than buying a generator big enough to start everything at once, the module holds back the heavy loads for a moment so the house stays covered by a smaller one. An annual maintenance plan and monitoring we manage sit behind it.

Standby generator questions from Farmingdale homeowners
Does a standby generator need a permit in Farmingdale?
A permanently installed generator normally requires New Jersey Uniform Construction Code permits, because it involves permanent electrical and fuel work. Depending on the property and the municipality, building, zoning, floodplain, utility or fire-code review can also apply.
How is the gas pipe size worked out?
From the generator's demand, the available pressure, the pipe length, the allowable pressure drop, the fittings, the pipe material and every other appliance connected to the system. The adopted fuel-gas code carries the sizing requirements and tables, and the model's published fuel consumption goes into the calculation.
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.
