When a utility outage occurs, the microprocessor controller signals the generator to start automatically. The system then waits for the generator to reach stable voltage and frequency before initiating the transfer sequence. Once stable backup power is confirmed, the switch opens the utility connection and closes the generator connection in an open transition mode. This break-before-make process prevents dangerous backfeeding or power surges. After utility power returns and stabilizes, the switch automatically retransfers the load back to the primary source. The controller then allows the generator to run through a cooling cycle before shutting down. This entire process happens without human intervention, ensuring critical loads remain powered seamlessly.\u003c\/p\u003e\n\u003cdiv style=\"margin-bottom: 16px;\"\u003e\n\u003cp style=\"margin: 0;\"\u003e\u003cspan style=\"font-weight: bold;
