Robert from Middletown, NJ has been a Green Sun Energy Services client since October of 2022. Six weeks after he signed the generator was running, a 22 kW Generac behind a 200-amp service-rated transfer switch with a surge protective device on the panel and two management modules sharing the heavy loads. The surge device matters more than people expect: the damage often arrives when the grid comes back, not when it goes down. A Generac service contract has covered it since. Middletown is in Monmouth County.

Thank you, Robert. Transparency is the easiest promise to make and the hardest to keep on a job with permits and inspections in it. The 22 kW Generac at your home in Middletown was installed with surge protection built in, so the machine protects the house and the house protects what is plugged into it. That is a high bar you have set us, and we will try to keep it.
Standby generator questions from Middletown homeowners
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.
Can it start during a brownout when the power is not fully off?
Yes. The controller monitors whether the utility supply is acceptable, not merely whether voltage is present, so it can start while some lights and appliances still appear to be working. That is usually the explanation when a generator runs during severe utility-voltage problems.
Does a generator produce less on natural gas than on propane?
Some models do have a lower rated maximum output on natural gas than on propane -- a current 22 kW machine is rated 22 kW on LP and 21 kW on natural gas. Other models carry their own ratings, so the model-specific specification sheet is what settles it rather than a general rule.
