Sam from Tinton Falls, NJ has been a Green Sun Energy Services client since March of 2021. The Generac 7042 at the house is a 22 kW machine on natural gas, feeding a 100-amp transfer switch, installed in February of 2021. Green Sun has serviced it every year since – March of 2021, January of 2022, February of 2023, March of 2024, February of 2025 and February of 2026. The machine carries a house of about 4,400 square feet, and the late-winter timing of its maintenance is deliberate: it puts the check after the season that tests a generator hardest rather than before it.

Standby generator questions from Tinton Falls homeowners
Will a 22 kW generator run an entire Tinton Falls house?
For many homes, yes, but that does not mean every load can run at the same moment. Houses with two central air conditioners, electric heat, EV charging, pool equipment or electric cooking may need load management or a larger machine. The answer comes from a load calculation rather than from the phrase whole house.
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.
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.
