Patent abstract
A circuit breaker that functions like a double pole double throw (DPDT) switch is used to isolate the commercial power grid from an external power source. When in the “on” position the circuit breaker serves as a main power input circuit breaker allowing power from the commercial power grid to feed into existing wiring. In the “off” position the commercial power grid is disconnected and isolated from the existing wiring. Instead, the switch mechanism is connected to an external power source such as a generator. The generator can be safely operated without risking power backfeed into the commercial power grid.
