Your right Ryan. For some reason I was remembering the section that used the words "Listed cord sets" and when I did find it, it was "Listed GFCI protection". Must be the CRS kicking in again.
OSHA 1926 subpart K would apply, The wire would need to be 12AWG and the connectors on the ends would need to be rated for use in that application. The practice of making up a 2g box on the end would be unacceptable.
