How a Standby Generator Works

A home standby generator system consists of two products: a standby generator unit and an automatic transfer switch. The two work in concert with your home to ensure when power is lost, it’s only for a matter of seconds before backup power kicks in.

A standby generator system and automatic transfer switch are professionally installed to your home’s existing wiring. Constantly at the ready, the system senses when utility power stops flowing to your home for any reason, thus sensing a power outage. Within seconds, the automatic transfer switch seamlessly transfers your home’s selected electrical circuits and appliances to backup power. Once the generator system senses utility power is back online, your home is automatically transferred back to utility power and the standby generator is shut down until it’s needed the next time.

Choose Between Natural Gas & Liquid Propane Generators

Standby generator systems operate on either natural gas or liquid propane vapor. Both natural gas and propane generators provide a seamless transition from utility to backup power. If your home already utilizes one fuel or the other, it makes sense to use what’s already available.
