can romex be used in commercial buildings
In fact, MC cable and romex both stand the same in the eyes of the code in terms of requiring protection from damage. Not true in my area anyway. My licensed electrician said that I can NOT use romex in a commercial building, he said it has to be protected meaning either conduit OR MC Cable.I don't know about commercial installs. AFAIK, nm is not allowed in commercial, so your comment doesn't really address my point.ot true in my area anyway.
