Alfred Vail Mutual Association in Shrewsbury Township, NJ has been a Green Sun Energy Services client since July of 2013. The generator was commissioned at the end of August, a 20 kW Generac behind a 200-amp service-rated transfer switch with a five year warranty, covering 3,385 square feet. A housing association has a different problem from a household: an outage affects everybody at once, and the community building is where people gather when it happens. Shrewsbury Township is in Monmouth County.

Standby generator questions from Shrewsbury Township homeowners
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.
Will a 20 kW generator run an entire Shrewsbury Township house?
For many homes, yes, but that does not mean every load can run at the same moment. Houses with two central air conditioners, electric heat, EV charging, pool equipment or electric cooking may need load management or a larger machine. The answer comes from a load calculation rather than from the phrase whole house.
Can it start during a brownout when the power is not fully off?
Yes. The controller monitors whether the utility supply is acceptable, not merely whether voltage is present, so it can start while some lights and appliances still appear to be working. That is usually the explanation when a generator runs during severe utility-voltage problems.
