Asagna and Amina from Warren, NJ have been Green Sun Energy Services clients since September of 2016. The generator was commissioned that November.
It is a 22 kW Generac on natural gas, behind a 300-amp transfer switch. The load survey recorded 5,000 square feet, a well pump and a sump pump. On a house with a well, an outage is not only a lighting problem: no power means no water at all, not even to flush, and that single fact usually decides both the size of the machine and whether the switch covers the whole service rather than a chosen few circuits. Here it covers the whole service.

Standby generator questions from Warren homeowners
Can a standby generator be installed in Warren without natural gas?
Yes. Residential standby generators commonly run on liquid propane. A properly sized tank, regulator and piping system has to be designed to deliver adequate vapour flow and pressure for the machine.
Does a 200-amp service need a 200-amp transfer switch?
A transfer switch installed in the service path has to be rated appropriately for the service and the configuration. A 200-amp service commonly uses a 200-amp service-rated switch, but the actual design is confirmed by the electrician rather than assumed from the service size.
How can a whole house be carried on a smaller electrical service?
Through load management. One or more large loads are controlled so they do not start at the same moment, or shut down briefly if generator demand climbs too high. That is what allows whole-house coverage where the raw sum of every connected load would otherwise exceed the machine.
