The room i want to install some vertical EMT (for data cables) has a horizontal electrical wire (romex or something like it), about 8 or 10 inches from the floor, going across the entire wall as near as I can tell.

Now there is enough give, that I could push the romex to one side and install the conduit, but there is more tension than I would like. Is there any issue with pushing the electrical off center, and rubbing directly against metallic conduit?

  • Could you use 1/2" standoffs to lay the conduit over the NM-B cable? I'd personally want the shielded wiring to be outside the cable for protection.

  • I'm not understandong the geometry here. Are the wires against the wall surface, or centered in a wall space (passage holes drilled in the middle of the 2x4s? How are the wires protected from nails from the other side of the wall? Nov 17 '17 at 16:28
  • Wire is centered via holes in the middle of the studs. No protection provided. Nov 18 '17 at 2:53

There is nothing wrong with having the NM-B in contact with the outside of some EMT. Just be sure it isn't located near a sharp edge.


If you use conduit hangers like these:

If will hold the conduit ⅜" away from the wall giving the NM cable plenty of room behind it.

Good luck with your project!
