A transfer switch is more than a convenient way to shift between power sources; it’s also an essential safety device. It returns power to the utility service when the generator is shut off.
The transfer switch prevents voltage from traveling from a home’s generator back to the grid and from the grid to your generator, a hazardous condition known as back-feed. Back-feed can cause electrocution to utility crews working on power lines, electrical fires, and damage to your generator. With professional generator transfer switch installation, you can safeguard your home and utility workers.

How an Automatic Transfer Switch (ATS) Works
- The utility power source fails because of a lightning strike, downed power line, or other failure.
- The transfer switch detects the voltage loss from the utility and immediately shifts the load to the emergency power source when power from the generator is stable and within the prescribed voltage and frequency tolerances.
- When the utility power is restored, the transfer switch retransfers the load from the backup to the normal power source.
