I have a dryer line hanging from the ceiling joist. Will it pass code if it's attached to the poured concrete basement wall? Do I need to put the wire through conduit? Thanks. enter image description here

  • Looks like it might also be a NEMA 10 rather than a NEMA 14 – Ecnerwal Jan 14 at 14:59

    BTW - that black line on the right of the picture looks like another electrical cable. If it is, it needs to be secured to the wall and protected as well. Make one chase (2 @ 2x4, on either side of the wires) to cover them both. – FreeMan Jan 14 at 17:09
  • @FreeMan Good catch. I thought it was a gas pipe...which probably also should have been secured, idk. But looking closely at it it might be a cable. Boxing in both together is a great suggestion: Install the dryer outlet box in the chase and you're done! Good idea. + – George Anderson Jan 14 at 22:02
  • That black line is coming from an air compressor. Thanks for the info. – john Jan 21 at 13:08

No, it's not.

It needs to be protected in conduit or a covered stud wall at least 8' up as measured from the floor. And, like others have said, it needs to be secured.

    Does the wall really need to be covered? Unfinished basements have wiring in them as far as the eye can see around here. – isherwood Jan 14 at 16:35

    @isherwood I believe technically it does. Imagine cable going thru drilled studs at about 4' (typical height) in an open wall. People could hang tools, equipment, cleaning equipment, etc on those cables. It would be stupid, but people do stupid stuff. Not sure if it needed when stapled to a stud vertically, but I think so. Again, if it's in joists along the ceiling and it's over 8' protection isn't needed. – George Anderson Jan 14 at 17:01
  • @isherwood The cable needs to have some sort of damage shield up to a certain height, that's a statutory requirement to keep it from getting struck by something. Most people just use a stick of EMT conduit coming out of a J-box up to the required height, then the cable just exits the conduit stick. – Harper - Reinstate Monica Jan 14 at 19:27
  • I have the wire running across the ceiling beams on a running board but the ceiling in my basement isn't 8 feet high. Does the wire have to be in conduit on the running board? – john Jan 14 at 21:39
  • Technically, probably yes. Where does the cable come from? Does it come from a panel on the main floor and pop out thru a bottom plate? Or? What you have now sounds pretty safe, except for the dangling outlet. But if and when you go to sell your home, it will get called out by a home inspector. Conduit is cheap, you can run your existing cable inside conduit, just make sure you get a large enough size to easily pull it. Cable is harder to pull than individual wires so go it bit larger than required. – George Anderson Jan 14 at 21:56
