When a utility outage occurs, the controller signals the generator to start immediately. The system then disconnects the load from the utility source safely. After a programmed delay, it connects the load to the generator power source. This break-before-make action prevents dangerous source-to-source connections. Once utility power stabilizes, the switch returns the load to normal utility power automatically.\u003c\/p\u003e\n\u003cdiv style=\"margin-bottom: 16px;\"\u003e\n\u003cp style=\"margin: 0;\"\u003e\u003cspan style=\"font-weight: bold; color: #1e3a5f;\"\u003ePower Source Monitoring:\u003c\/span\u003e \u003cspan style=\"color: #444;\"\u003eThe microprocessor controller continuously senses voltage levels on both utility and generator inputs.
