Here is a hard wired curly cord drop that is connected to a stationary gondola, inspector says it's legal, but I would say it is not because it is replaceing permanent wiring with rubber cord. All other gondola drops are power poles.
I believe you're right, but without knowing theactual wire type and correlating it to the listed wire types in the NEC and teir permissible installation methods and use, can't say for sure. (Not that I can THINK of any types that would permit this installation.)
