  • NM-B to PVC conduit

    I am running ellectric to a pool heat pump. I am using NM-B in the unfinished basement and PVC conduit out under a deck to the disconnect box. Since the NM-B has THHN wire can just strip the sheating going into the condiut or do I need to use a junction box?

    That wouldn't pass inspection here. THHN is not approved for wet locations. THWN is. Almost all stranded wire rated THHN is THHN/THWN now. Junction box, THHN/THWN in conduit to the disco is the way to go.

      Thanks, I'll use a junction box.
