My distribution panel's neutral bar is grounded. So I have only two wires coming out of the panel to the GFCI receptacle. The inspector tested the receptacle and said it's not GFCI.
I wonder if it's because I left the GFCI's ground entrance empty? If that's the reason, can I just connect it to the neutral, which is grounded already?
And, does the code require GFCI has to connect with 3 wires? 2 Wire is not OK?
