This video gives a general overview of working and automatic operation of an emergency power backup generator and transfer switch by Cummins Onan.
An average home may use more than a hundred electrical appliances and devices to provide convenience, comfort and security. A residential generator has major advantages over a portable gen set- automatic start, permanent fixture, more power, cleaner fuel (natural gas or propane), low running costs and all-weather operation. Standby power systems start automatically with seconds after a home's electricity goes out and ensure a continuous electrical supply.
A Transfer Switch immediately senses when power is interrupted and transfers power generation to generator. It also senses when power is restored and transfers the load back to the utility source and signals the generator to shut down. The power generator is installed outdoors and linked directly to home's permanent fuel supply. The Service Entrance Breaker provides protection to your transfer switch, internal breakers and circuits and generator due to electrical strikes and power surges.
