Am going to be wiring a detached garage, owner wants 1 20A circuit for a couple of keyless and 2 receptacles. I get a call from the cement contractor, he tells me that the building inspector won't let him pour the footings until a ground rod is driven and attached to the footing rebar. As far as I know if your only putting 1 branch circuit to the structure, there are no requirements for footing steel as part of the grounding electrode system. Am I wrong?
