The flexible cord used in this installation was connected with a fitting that wasn't designed for this purpose. And even if it was designed specifically for this cord, it still can't be used for the permanent supply to stage equipment. Flexible cords can't be used as a substitute for fixed wiring under any circumstances (400.8).
In addition, the metallic cable assembly that runs from the cabinet to the device box enclosing the receptacle isn't properly secured, and the fitting that was used may not be designed for this use. Per 110.3(B), listed or labeled equipment shall be installed and used in accordance with any instructions included in the listing or labeling.
See Art. 320 and Art. 330 for specific support requirements for these types of wiring methods. See 320.30 for securing and supporting Type AC Cable and 330.30 for securing and supporting Type MC cable.
