The Generac 200A Service-Rated Automatic Transfer Switch provides the critical connection between a compatible Generac standby generator and a home's electrical system, automatically transferring electrical loads to generator power when utility service is interrupted.
Rated for 200 amps and 120/240V single-phase residential service, the transfer switch is designed for whole-home backup applications where automatic operation is essential. When utility power fails, the system works with a compatible Generac standby generator to transfer the home's electrical load to backup power—without requiring the homeowner to manually operate a transfer switch.
Its service-entrance-rated design allows the unit to serve as part of the home's primary electrical service equipment when properly configured and installed. The durable NEMA 3R enclosure supports both indoor and outdoor installations, providing greater flexibility when designing a residential backup-power system.
Integrated load-management capability can also help prioritize available generator capacity. The system can manage up to four HVAC loads without additional hardware, helping balance larger household electrical demands against available generator output.
