Cecilia and Mike from Metuchen, NJ have been Green Sun Energy Services clients since January of 2021. The machine is a Generac 7043-2 rated 22 kW on propane and 19.5 kW on natural gas, running on natural gas, on a 200-amp transfer switch, and it was commissioned in August of 2021. At about 4,565 square feet this is one of the larger houses on a 22 kW machine, which is where the load calculation stops being a formality: the number that matters is what runs at once, not what is installed. Green Sun has serviced it in September of 2022, October of 2023, September of 2024 and September of 2025.

Standby generator questions from Metuchen homeowners
How close to the house can a generator sit in Metuchen?
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.
Can the generator stay connected during a pressure test?
The machine has to be protected from test pressures beyond what its fuel controls are built to withstand. The fuel-gas code sets out when appliances are disconnected or isolated for testing, and the plumbing contractor follows both that code and the generator's installation instructions.
Does the generator have to be bolted down?
Not every ground-level installation uses the same anchoring method. The requirement changes with the model, the pad type, wind exposure, flood requirements, elevated platforms and any local engineering requirement. The model manual and the site conditions decide it.
