When I got the power turned on the inspector said, "wow that's a long ground wire, check." I didn't even know it was copper until it was cut off; it's so tarnished on the outside (no sheathing). It's probably at largest, 10 gauge too.

Maybe I'll run a new wire from the ground bus in the breaker box.
