During an inspection of a living room, I came upon a Romex cable that was run from an on-the-wall switch box, wired to a standard male 3-prong plug, which was plugged into a standard receptacle. I tagged this in my report because the Romex was within 6-7 feet of the floor and wasn’t covered or enclosed in a raceway. I also cited the fact that Romex isn’t intended to be used as a flexible “extension” cable. Obviously, the switch box should have been hard-wired.
What I’m wondering is, is it an actual code violation to use Romex with male or female 3-prong plugs? I would have liked to have cited an actual code violation if one exists.
Also, if the Romex connection is, in fact, a code violation, then would it have been OK to run a regular flexible cord (in some kind of raceway) from the switch box, connected to the male 3-prong plug, and then plugged into the receptacle?
Thank you in advance to anyone who can help me.
