5. Instrucciones de funcionamiento
The Generac RXSC200A3 transfer switch operates automatically in conjunction with your Generac standby generator's controller.
5.1. Operación automática
- Utility Power Available: The transfer switch directs utility power to your home's electrical panel.

- Utility Power Restored: When utility power returns and stabilizes, the transfer switch automatically transfers the electrical load back to the utility. The generator will then enter a cool-down period before shutting down.
5.2. Manual Operation (Emergency Override)
In emergency situations or for maintenance, the transfer switch may have a manual override function. Refer to your specific generator and transfer switch owner's manuals for instructions on safe manual operation. Always ensure the generator is off and locked out before attempting any manual transfer.
