Home Generator Interlock Kit for a Cutler Hammer Loadcenter Copyright-460x345-WireThroughWall-IMG_6702_2


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.

You can see the 10/3 Romex as it penetrates through the drilled hole in the rim joist in order to come into the back of the generator inlet mounted outside.

Duct Seal was also used inside where the 10/3 Romex penetrates through the rim joist to prevent air from coming into the basement.
Note how tightly twisted together the #8 wires are before the blue wire connector is screwed on.
