What is an Automatic Transfer Switch?

An Automatic Transfer Switch (ATS) is a crucial component in a standby generator installation that allows for the automatic switching of electrical loads between the utility power source and the generator.

Generac offers a full line of residential single-phase transfer switches to meet any
need when paired with our home standby generators. These flexible solutions
ensure that you get to cover exactly what is needed.

How Does A Transfer Switch Work?

When power from utilities is disrupted, your whole-home generator will power on and prompt the ATS to transfer the electrical load to the back-up power source. As soon as utility power is restored, the generator controller will confirm a return of stable voltage and signal the switch back to utility power.
