## HOW HOME BACKUP POWER WORKS

A Generac automatic home standby generator is a permanently installed backup power system designed to protect your home during power outages. Unlike portable generators, it’s connected directly to your home's electrical system and powered by your existing natural gas or liquid propane supply—so there’s no need to refuel or run extension cords.

Here’s how it works: The generator is paired with an automatic transfer switch that constantly monitors your utility power. When the power goes out, the transfer switch signals the generator to start. Within seconds, the generator powers on and takes over, supplying electricity directly to your home’s electrical panel. Once utility power is restored, the system automatically shuts down the generator and reconnects your home to the grid.
