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.

A two screw metal Romex connector was used to secure the10/3 Romex to the CH circuit breaker panel.

The 10/3 Romex is stapled along the rim joist using BX staples.
