Sparky,
(Serious question)
Many times one of the utilities has bonded to the original GEC with a split bolt and it was closed up in the wall or ceiling. can't always be sure if something is using it or not. I guess the question really is if there is any harm in leaving it?
Hey, what if all the 3 prong receptacles were installed on old 2 wire cable and bonded to that old GEC as it ran past. If you cut it all your Grounds are then NG (we're PG rated here).
What do you think?
