An automatic standby generating system typically has three basic elements: a generator, a transfer switch and a service-entrance breaker.
- Generator – Produces electricity for essential circuits, such as heating, air conditioning, refrigeration, security and lighting. Your backup needs, simple or more extensive, determine the size and output of the unit.
- Transfer Switch – Immediately senses when power is interrupted and transfers power generation responsibility to the generator. Senses when power is restored and transfers the load back to the utility source and signals the generator to cool off and shut down.
- Service Entrance Breaker – Provides protection to your transfer switch, internal breakers and circuits and generator due to electrical strikes and power surges. See below for the step by step process of a Generator Installation:
