The bathroom includes a GFCI outlet that will not reset. Research revealed that such outlets do seem to stop working sometimes. So I am attempting to replace the outlet.
After pulling the faceplate off, I found an unexpected situation in the junction box. 3 wires come into the box, and the same 3 wires leave. There are black, red and white leads.
The black lead comes in and is directly spliced to the outgoing black lead with a wire nut. It is not connected to the GFCI at all.
The red lead is wired to hot on BOTH the load and lead terminals of the GFCI. Likewise, the white lead is wired to neutral of both the load and lead terminals.
The red and white wires are both continuous in that they come into the box and leave the box without a break or splice. In each case, the insulation was stripped in the middle of the wire to allow it to wrap around the terminals of the outlet.
- Is this wired correctly, and if not, how do I rewire it so that it is?
My instinct says that I should wire it so the incoming red and white leads are wired to the hot and neutral on the lead side, and that the outgoing red and white leads should be connected only to the hot and neutral load terminals. I don't know what is downstream, but I believe whatever it is would be GFCI protected at that point.
- Is it okay to strip insulation in the middle of a wire this way? I mean it works, but is it code compliant?
If it's important to know where the hot and neutral wires eventually terminate, that will require more investigation... who knows what's been done. Not a single thing in this house has ever been done correctly as far as I can tell (e.g. built-in microwave is powered from a lighting circuit instead of having a dedicated 20 amp branch).
