GFCI wall outlet in unfinished basement
"RBM" wrote in message
... "Beta-42" wrote in message ... I want to add a surface-mounted GFCI outlet on the wall in an unfinished basement (for a washing machine). The wiring going to the outlet will be 12/2 NM. I think I can figure out how to do it if I just use a metal box and metal conduit. But, I am wondering if there is a way that I can do it using plastic/PVC instead of metal. I am thinking of using this type of PVC box: http://www.grainger.com/Grainger/items/4FYW1 , and then running the 12/2 NM wire down along the wall through 1/2-inch PVC conduit to get to the box. If I do that, my question is, "Is there some type of fitting or adapter that goes on the top end of the PVC conduit where the 12/2 NM enters the PVC conduit?" If so, is that type of fitting shown anywhere in this product brochure?: http://www.kraloyfittings.com/downlo...loy%20ftgs.pdf Thanks. The pvc and pvc box is fine. If you can't run the conduit continuous into the breaker box, terminate it in a 4" square metal box adjacent to the panel, then from that box into the panel. The fittings you would use are called male adaptors Thanks. I think I may have mistakenly described this as having the 12/2 NM feed to the outlet running horizontally along the wall from the breaker box to the outlet. That is not the case. The 12/2 NM feed from the breaker box will be up in between the ceiling joists and then will run "down" (meaning vertically down) along the wall to the outlet. Where it runs down along the wall it will be enclosed in the PVC conduit. So, I am assuming that I can just have the 12/2 NM feed enter the vertical PVC conduit above the outlet in between the ceiling joists. And, I am trying to figure out if I need to put some type of fitting there where the NM enters the conduit. I know that if it were metal conduit I could put a fitting there that would clamp onto the NM and clamp onto the metal conduit. But do I need something like that when using PVC conduit? I don't see any similar fittings in PVC like the ones I see for metal conduit. |

That requires an accessible box above to transition to. I think you are overengineering this. You said unfinished so I'm assuming the wall studs are accessible. If you are able to staple the 12/2 along the side of a wall stud I believe that is all that is required for protection in an unfinished space. You can also mount a normal box against the same wall stud. |

You need to put a male adapter with a plastic threaded bushing on the end of the pvc where the nm enters it, and the cable must be stapled to the joists withing 12" of that point. as per NEC334.15C |
