Home Generator Interlock Kit for a Cutler Hammer Loadcenter Copyright-460x717-LoadCenterInterlockKit-6767-Cutout


Note how the number 10 bare copper ground wire is shaped in the rear of the generator inlet box and then wrapped around the green ground screw using the included clamp.

This is the completed interlock kit installation on an older Cutler Hammer type CH circuit breaker panel (AKA Loadcenter).

The interlock kit functions as a transfer switch without having to install a separate box with additional wiring that also requires additional wall space.

The red tape marks on some of the circuit breakers are there so that the homeowner can easily identify some of the critical circuits that will require generator power. These include the heating system, the well pump, and the refrigerator. The bathroom and kitchen lighting circuits are also identified.
The upper red arrow points to the generator ground connection. The lower red arrow indicates the white neutral wire connection. This is the main panel so the ground and neutral are connected on the same terminal bar. In a sub-panel the ground and neutral would be kept separate.
