John from Neptune, NJ has been a Green Sun Energy Services client since December of 2020. The generator was commissioned in August of 2021: 14 kW on natural gas, on a 200-amp service-entrance switch with two smart management modules and surge protection. The load calculation asked for 13 kW across the 1,919 square foot house, and two sump pumps are most of the reason for that figure – a pair usually means a basement that has already proved it needs them, and both can want to run at once in exactly the rainfall that takes the power down. Two refrigerators, a separate freezer, an electric oven, a washer, a gas dryer and a dishwasher fill out the load. The five-year maintenance plan ran its full term and has since expired.

Standby generator questions from Neptune homeowners
How far from the property line does a generator need to be in Neptune?
There is no single statewide New Jersey property-line setback for a residential generator. Setbacks are set by the municipality's zoning ordinance, so the requirement is a Neptune question rather than a general one. A generator can meet every manufacturer clearance and still breach a side-yard or rear-yard setback, which is why the zoning review happens before the location is fixed.
Should gas pressure be checked while the generator is running?
Yes. Operating pressure means more than a static reading taken with the generator off. The fuel system has to hold adequate pressure while the generator runs and other appliances may also be drawing gas. That matters most when an existing residential service is being reused.
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.
