Neutral Bar

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.

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.

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.
This is the location that the homeowner chose to have his portable generator sit and operate during a power outage.
