Anti-Backfeed Circuit Breaker

Reference#: P01517


External circuit breaker boxes and associated wiring, while allowing the user to select circuits to be powered by the generator using existing circuit breakers and existing house wiring, are costly. As is the needed power company rental collars or other rental devices.

An easily installed device is described which allows for hook-up of portable generator-supplied power to existing home AC wiring. Failsafe mechanical means are provided to prevent backfeed of generator power into commercial mains. Once installed, this device can be easily and safely used by the homeowner for switching generator power to house circuits, and for removing such power and switching back to the power company grid as necessary.
