Wire Through Hole Duct Seal

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.

Duct Seal was also used inside where the 10/3 Romex penetrates through the rim joist to prevent air from coming into the basement.

The 10/3 Romex is secured to the rim joist using BX staples.
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.
