@audphile1 Not a bad idea, I already have two circuits, and could just rewrite one of them.
@jmrrobbie1 As it happens, due to a small addition to our house a few years back, we had the panel upgraded to 200 amp service and buried to the pole. The grounding cable is a large braided copper line that runs to the other end of the basement to the copper water line. All well done and inspected.
