We are having this discussion on our intranet forum. What do you guys think of this?
In a case where a paralleled feeder using multi-conductor cables and where the standard ground conductor size is not adequate for the OCPD per NEC 250-122. A new properly sized equipment grounding conductor must be installed. Should there be a note to the installer that he/she cut the original (now undersized) equipment grounding conductor back to the jacket and only connect the new adequately sized equipment grounding conductor? Or what would be a better method of installation?
