What is a transfer switch? Transfer Switches are an integral part of the power generation process, allowing smooth and immediate transfer (Automatic or Manual) of electrical current between multiple sources and the load.	Patriot Series Automatic Transfer Switches Available from 100A to 1250A
Why put transfer switches on a generator? When the generator is operating, the transfer switch prevents dangerous feedback of current to the utility's system. It also ensures that different power sources are fully synchronized before their power is combined or loads are transferred, which is imperative for safe operation.
How does it work? The transfer switch senses when utility power is interrupted, and starts up the generator if the utility power remains absent. In about five to ten seconds, when the generator is producing full power, the transfer switch disconnects the load from the utility and connects it to the generator, restoring electricity to the load. The transfer switch continues to monitor utility power, and when it is restored, switches the load from the generator back to the utility. Once the generator is disconnected, it goes through a cool-down routine and is automatically shut down.
