SYSTEM DIAGRAM
The automatic transfer switch is the key component of your backup 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 the utility power.
Lennox’ generator systems include commercial-grade automatic transfer switches in a
variety of amperage sizes and configurations to match your home’s power needs.
