This photo was taken in an industrial plant. The plant uses a lot of, pre-assembled, multi-conductor, flexible cables with MTW outer jacket insulation. These cables are usually run in cable tray. Each end of the cable has a male or female screw-on connector. There is a 15hp, 3 ph, 480 volt motor fed from the starter with one of these 50 foot, 6-pin cables. The connector at the motor disconnect failed. To get machine working, for production reasons, the bad connector/plug had to be cut off and it was discovered inside the cable a green #4 wire was used as one of the 480v power conductors and a red #4 wire was the ground (after some fuses were blown). The other two #4 power conductors were black and yellow. There were also two #14 wires for 120v pwr to unit. Even though these pwr conductors were internal to the cable and usually never accessed.… Is this a code violation?! Any comments would be appreciated.

Thank you all.
