Christine from Middletown, NJ has been a Green Sun Energy Services client since August of 2020. A Generac Guardian rated 22 kW on propane and 19.5 kW on natural gas went in that October, running on natural gas behind a 200-amp automatic transfer switch. The load survey put 5,000 square feet of living space behind it, which is what puts the machine at the top of the air-cooled range rather than in the middle of it – and with the switch sized to the whole service, an outage takes nothing off the table.

Standby generator questions from Middletown homeowners
Does a generator in Middletown have to sit twelve inches above the flood elevation?
That figure should not be treated as a universal rule without looking at the actual property. The required elevation can depend on the flood-zone designation, the municipal freeboard, the Design Flood Elevation, Coastal A or V Zone conditions, NJDEP requirements and the applicable building-code provisions. Each flood-zone installation is worked out individually.
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.
Can a standby generator run central air conditioning?
Yes, when it is sized for it. The design has to account for both the running demand and the starting surge of the air-conditioning equipment. Load-management equipment can be used where necessary so that demand does not all arrive at once.
