A Generac 20 kW natural-gas standby generator maintenance plan:
The standby generator at this Atlantic Highlands home was originally installed in October of 2017. The unit is a Generac 7000 Series (model 7038-1) rated at 20 kW on liquid propane or 18 kW on natural gas; this installation runs on natural gas supplied by JCPL. A 90-amp transfer switch supports managed whole-house load coverage, meaning the system monitors and cycles loads automatically so the generator is not asked to carry more than its rated capacity at once.
In September of 2026, the homeowner enrolled in Green Sun Energy Services’ PowerBase Silver Plan. The plan provides scheduled maintenance visits designed to keep the generator in verified working condition between outages — checking fluid levels, exercising the unit, inspecting electrical connections, and confirming that the automatic transfer switch responds correctly. A generator that sits unused between storms can develop faults that only show up when the grid goes down; scheduled maintenance catches those faults while there is still time to correct them.

Standby generator questions from Atlantic Highlands homeowners
Does the transfer switch need flood protection as well as the generator?
Yes. A flood review should cover much more than the generator enclosure. FEMA recommends that a residential standby system consider elevation or protection of the generator, the transfer switch, the normal and emergency panels, the feeders and the control wiring together.
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.
How far from the property line does a generator need to be in Atlantic Highlands?
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 Atlantic Highlands 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.
