Article talks about receptacle replacement. Changing out two prong receptacles and replacement them with grounded one. The use of GFCI in the place when there no ground.
replacing a nema-1 where no egc exists for a nema-5-gfi or nema-5 with gfi ocpd. sounds good. i don't like that rule, but whatever NEC says is it :thumbsup:. just be sure the little "no egc" sticker is on the faceplate.
Just to add, if there is an EGC in any cabling between grounding receptacles used on a non-grounding circuit protected by a GFCI, you should not connect it to any receptacle terminal or box.
The reasoning is that a line-to-case/housing short within any plugged in appliance or equipment does not energize the case or housing of another appliance or equipment on the same circuit.
