Guys,
I disagree. The ground that the manufacturer is requiring is not part of the Grounding Electrode System. I would think if the manufacturer ask that the equipment be grounded to a water pipe and they don't specifically say "within 5 ft. of the entrance to the building", then they are just looking for the metal case to be bonded. Doesn't 250.130 (c) (1) and (2) allow a non-grounding receptacle to be replaced or a branch circuit be extended and be grounded to "any accessible point on the Grounding Electrode System or any accessible point on the Grounding Electrode System. It doesn't seem to say within 5 ft. of the entry to the building...or am I reading this wrong?
