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 PB-30 generator inlet box comes with a factory installed green grounding pigtail. Consult article 250 in the National Electrical Code for information on grounding.

Here is the finished generator inlet. It just needs a small bead of clear caulk at the top to keep water from getting behind it. Article 702 in the National Electrical Code pertains to generator installations, but other articles in the code book also apply to the wiring methods used in this installation.
Duct Seal was used to seal the hole from air and moisture.
