Joe from Middletown, NJ has been a Green Sun Energy Services client since April of 2020. The generator was commissioned that June, on a house of 4,786 square feet with two heat pumps, two dishwashers, two refrigerators and two sump pumps on the survey. Connected load came to 20 kW and the machine is rated 19.5 kW on natural gas, so a load-management module is what lets it carry the whole house rather than a chosen set of circuits: the largest loads are held apart, and the total never arrives at once. The household later moved to Shrewsbury and had a second generator installed there, written up here.

Standby generator questions from Middletown homeowners
What is a service-entrance-rated transfer switch?
One that is listed for use as service equipment when installed in the appropriate configuration. These are commonly used for whole-house systems, where the transfer switch becomes part of the home's service arrangement rather than sitting downstream of it.
Can a generator be raised on a platform?
Yes. Manufacturer guidance specifically covers installations on platforms and other supporting structures, and directs them to the applicable fire-safety standard, including a noncombustible surface extending beyond the generator for the configuration addressed. Flood and structural requirements have to be satisfied as well.
What happens if the manufacturer and Middletown 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.
