Kate from Rumson, NJ has been a Green Sun Energy Services client since February of 2025. The Generac 5243 at the house is rated 16 kW on propane and 15 kW on natural gas, runs on natural gas, and feeds a 65-amp transfer switch. It was installed in February of 2010 by another company, which makes it the oldest machine Green Sun currently looks after. Green Sun’s first visit was in April of 2025. A machine on its sixteenth year is the strongest argument there is for an annual service: nothing else explains one still starting when far newer ones have not.

Standby generator questions from Rumson homeowners
Which fuel-gas code applies?
New Jersey currently adopts the 2024 International Fuel Gas Code as its Fuel Gas Subcode, which is what governs the piping, testing and shutoff arrangements on a natural-gas generator installation.
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 Rumson?
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.
