Abstract
A transfer mechanism is provided for transferring the supply of power between a generator and utility source. The transfer mechanism includes a monitoring system for monitoring the power supplied by the utility source. The monitoring system starts the generator in response to a power outage from the utility source and stops the generator in response to the restoration of power from the utility source. A power relay has a utility input connectable to the utility source, a generator input connectable to the generator, an output connectable to a load, and a movable contact for selectively interconnecting one of the inputs to the output in response to the generation of power by the generator.
