Diane from Belford, NJ has been a Green Sun Energy Services client since April of 2021. The generator was commissioned that December: 14 kW on natural gas, on a 100-amp service-entrance switch with a smart management module. A 100-amp service is the constraint that shapes a job like this – there is less headroom than a modern 200-amp panel allows, so the management module is what makes whole-house coverage possible at all rather than an optional refinement. The calculation asked for 12 kW across the 1,288 square foot house, with a sump pump, two refrigerators, a washer, a gas dryer and a dishwasher to carry. The generator is supported by annual maintenance, an extended parts-and-labor warranty, and monitoring we manage.

Standby generator questions from Belford homeowners
Does a 200-amp service need a 200-amp transfer switch?
A transfer switch installed in the service path has to be rated appropriately for the service and the configuration. A 200-amp service commonly uses a 200-amp service-rated switch, but the actual design is confirmed by the electrician rather than assumed from the service size.
Does a standby generator need a permit in Belford?
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.
Can the existing natural-gas service in a Belford home supply a generator?
Often yes, but the gas system has to be evaluated first. The review covers the generator's BTU demand, meter capacity, available pressure, regulator capacity, pipe diameter and length, and every other gas appliance in the house -- furnace, boiler, water heater, range and fireplace among them.
