Automatic Transfer Switch—
The critical component of home standby power

The automatic transfer switch is the key component of your home standby power system. When an outage occurs, it automatically transfers power from the utility to your generator. When utility power is restored, the transfer switch signals the generator to shut down, and puts your home back on utility power. Lennox offers commercial-grade automatic transfer switches in a variety of amperage sizes and configurations to match your home's specific power needs.

Your Lennox dealer will determine the most appropriate automatic transfer switch based on your home and power preferences.
