Question:

I have a ungrounded GFI outside that I just can't ground, is that violating and CODE? I live in Bolingbrook IL.

Scott Johnson

A

Answer:

Hey Scott thanks for your question. It is not clear what you mean by "just can't ground" and what type of GFCI device. "GFCIs are intended to be used only in circuits where one of the conductors is solidly grounded." is a statement for Ground-fault Circuit Interrupters, KCXS in ULproductspec. This means that the system supplying the circuit with the GFCI must be grounded. Additional information is available at:

Receptacles on 15 and 20 ampere branch circuits must be of the grounding type as stated in 406.4(A). The grounding contacts must be connected to an equipment grounding conductor as stated in 406.4(B)&(C). There are other rules for replacements in 406.4(D) but you didn't mention that this is a replacement situation. If this is not the question you are asking please send in a follow up question.
