Non grounded GFCI receptacle

[John Gromkoski]

Does the NEC allow non-grounded GFCI? As long as it is labeled "non grounded"?

[Robert Ernst]

I believe so. Also Nachi says it's ok.

Non-grounded GFI's are fine. One side note; the three light tester will not trip them.

Interesting. Didn't know that about the three light tester. I was calling these out as defective. I guess I will need to test them with the receptacle's Test button also from now on. Does the Sure Test tester trip them?

I don't believe there is a requirement or need need to label "non-grounded".

Yes, if you have the ground-continuity adapter.
