- Can Romex (NM-B) be run through conduit? 2 answers
If I'm adding some new receptacles to a garage, and the wiring will be run surface-mounted to walls and ceilings, I think protecting the wiring with EMT conduit is probably a wise way to go.
I'm seeing some conflicting information as to whether it's OK to run NM-B (e.g. romex) inside EMT tubing. The more typical application is individual THHN conductors inside EMT. Rather than having to buy two types of wiring, is it OK to run the NM-B inside the EMT? Are there any special considerations?
