Steve from Lebanon, NJ has been a Green Sun Energy Services client since October of 2025. The 20 kW Generac at the house was installed by another company in November of 2012 and had been running for thirteen years when Steve brought its servicing to Green Sun. The first visit was a startup service – the full commissioning check a machine gets when it comes onto the plan, rather than a routine annual – taking in the spark plug and air filter, oil and filter, battery, load test and diagnostics, on a unit running natural gas behind a 90-amp transfer switch.

Standby generator questions from Lebanon homeowners
What happens if the manufacturer and Lebanon disagree?
The installation has to satisfy all applicable requirements. A manufacturer's listing cannot be ignored, and a manufacturer's minimum clearance does not cancel a municipal zoning requirement. Where requirements conflict or the interpretation is uncertain, the Authority Having Jurisdiction is consulted before the work goes in rather than after.
Can the generator be connected to any nearby gas pipe?
No. The branch supplying the generator has to be sized for the flow and pressure the machine needs. A pipe that happens to be close by may be too small, or may already be carrying too much load. Undersized piping shows up as poor starting, unstable running, reduced output or a generator that shuts down under load.
How is a standby generator grounded?
The grounding and bonding arrangement depends on the transfer-switch configuration, and in particular on whether the neutral is switched and the generator therefore treated as a separately derived system. It is designed by a qualified electrical contractor rather than assumed from another installation.
