Rick from Hamilton, NJ has been a Green Sun Energy Services client since February of 2024. A Generac Guardian rated 18 kW on propane and 17 kW on natural gas went in that April, running on natural gas behind a 150-amp automatic transfer switch. The load survey put 2,495 square feet of living space behind it. The switch is the part worth noticing: at 150 amps it sits between the essential-circuits panels and a full 200-amp service, which is what a house of this size with a moderate service actually needs rather than what a catalogue would sell it.

Standby generator questions from Hamilton homeowners
Why does the generator run when the power is on?
It is performing its automatic exercise cycle, which confirms basic engine operation and keeps the machine ready. A generator can also start because utility voltage has become abnormal even though the power has not gone off completely -- the controller watches the quality of the supply, not simply whether it is absent.
Does new gas piping have to be pressure tested in Hamilton?
Yes. Gas piping subject to the adopted fuel-gas code must be inspected and tested before it is accepted. New Jersey adopts the 2024 International Fuel Gas Code, which governs the inspection, the test pressure and how long the test has to hold.
How does the starting battery stay charged?
The system includes battery-charging provisions so the starting battery stays ready while the generator waits for an outage. A charging fault, a blown fuse, a wiring problem or simply a tired battery can stop a generator starting when it is needed, which is why battery condition is part of routine maintenance rather than an afterthought.
