I have found plenty of helpful diagrams and posts on connecting my planned detached garage subpanel to the main service. Routing the two hots, neutral, and ground to the subpanel via the underground conduit and making the service entrance to the outbuilding are easily understood.
Now for what might be obvious to everyone but me - for the physical connection from the subpanel to the grounding rod, what is the best way to route the ground wire? This is new construction so I don't have to contend with an interior wall or insulation. Is it as simple as drilling a hole in the exterior wall and weatherproofing around the hole after pulling the wire through or is there a gland plate /bulkhead that improves this connection? As I said, it may be something I've missed, but I can't say that I've seen a clear picture or video on this part of the plan.
Thanks in advance.
