Can I use Romex® (NM-cable) with a male plug connected to a receptacle outlet.
Monday, September 6, 2021
Using NM-cable with a male plug connected to a wall receptacle is not acceptable for multiple reasons:
1) NM-cable uses stiff, solid wire and is rated only for permanent installation between electrical boxes. Also, the cable must be protected from damage (not exposed).
2) Wall receptacles are connection points for flexible cords with a male plug (cord connector) for temporary use and removal.
3) Cord connectors are not rated for use with solid wire conductors.
4) It is not a recognized wiring method.
Yes, we know you are not intending to unplug it once installed, and “it oughta be alright,” but NM-cable with a male plug is not code-approved or acceptable.
