Karen from Red Bank, NJ has been a Green Sun Energy Services client since August of 2020. The Generac 6551 at the house is rated 22 kW on propane and 19.5 kW on natural gas, runs on natural gas, and feeds a 100-amp transfer switch. It was installed in December of 2012 by another company. Green Sun serviced it in September of 2021 and April of 2022. On a machine from 2012 the annual visit is what separates one that still starts from one that has quietly stopped being ready.

Standby generator questions from Red Bank homeowners
Can Red Bank require a generator to sit farther from the house than the manufacturer does?
Yes. Another applicable requirement can result in greater separation than the manufacturer's listed minimum -- equipment may be permitted eighteen inches from a qualifying wall while the local ordinance requires several feet from a property line. Both requirements have to be satisfied; neither cancels the other.
What gas pressure does a generator need?
It is model-specific and has to be read off the specification sheet rather than assumed. A current 22 kW model, for instance, specifies a minimum natural-gas pressure of 3.5 inches water column. Different models carry different requirements.
Does the residential building code apply to a generator?
It can. For applicable one- and two-family dwellings New Jersey adopts the 2024 International Residential Code, subject to state amendments. Structural and flood-related generator installations may therefore need review under the residential subcode as well as the electrical and fuel requirements.
