Philip and Fran from Farmingdale, NJ have been Green Sun Energy Services clients since July of 2021. A Generac Guardian rated 22 kW on propane and 19.5 kW on natural gas went in that December, running on natural gas behind a 150-amp automatic transfer switch, with 3,000 square feet of living space behind it on the load survey. A 150-amp switch sits between the two common sizes, and it is a choice rather than a default – matched to what the service actually draws instead of rounded up to 200.

Standby generator questions from Farmingdale homeowners
How close to the house can a generator sit in Farmingdale?
For the air-cooled models covered by the manufacturer's listed installation guidance, the rear of the generator can be as close as eighteen inches to a qualifying structure when every condition of that listing is met. That eighteen inches is a tested installation dimension, not a zoning setback, and a municipality can require more.
What does a standby generator sit on?
A stable, level support system allowed by the model's installation instructions. Depending on the machine and the site that can be an approved composite base, a prepared aggregate base, a concrete pad, or an engineered elevated platform.
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.
