Possibly someone can help me answer a question I have regarding: NEC - ‘406.4(D)(2) Non–Grounding-Type Receptacles.”
My understanding of this code is that the old, not-grounded, 2-prong receptacles can be replaced with a GFCI receptacle, so long as the GFCI receptacle is marked, ” “GFCI Protected” and “No Equipment Ground.” This is clear.
Can someone help me understand the NEC rationale for sub-paragraph (c)?
Sub-paragraph (c) of this code states, “(c) .... Grounding-type receptacles supplied through the ground-fault circuit interrupter shall be marked “GFCI Protected” and “No Equipment Ground.” An equipment grounding conductor shall not be connected between the grounding-type receptacles.”
Sub-paragraph (c), I don’t get. Why does the NEC on one had allow “Grounding-type receptacles s supplied through the ground-fault circuit interrupter “ and on the other hand say, “An equipment grounding conductor shall not be connected between the grounding-type receptacles.”
Here’s my question: What’s the purpose for allowing grounding-type receptacles downstream from a non-grounded GFCI receptacle , if the NEC says you’re not permitted to plug a grounded 3-prong-plug (equipment grounding conductor ) into that receptacle? Why not just use 2-prong receptacles marked “GFCI Protected” downstream from the non-grounded GFCI receptacle since 3-prong plugs at those outlets are not permitted according to to my read of 406.4(D)(2)(c)?
Thanks for your feedback.
