- Utility Power Loss: When the transfer switch detects a loss of utility power, it signals the standby generator to start.
- Generator Power Transfer: Once the generator reaches its operating speed and voltage, the transfer switch automatically disconnects from utility power and connects your essential circuits to the generator power.
- Utility Power Restoration: When utility power is restored, the transfer switch monitors the utility source for a stable return.
- Return to Utility: After a pre-set delay, the transfer switch automatically disconnects from generator power and reconnects to utility power. It then signals the generator to cool down and shut off.
