The Company I work for requires external grounds for 480v Cord fed equipment eg. Welders, portable fans, etc. This external ground is required in addition to the 4th conductor(green) in the molded cord assembly. Their standard requires a bare ground wire to be attached to the frame of the equipment and to the plug shell at the point of connection. My question is this, what does the code say about parallel grounding paths for cord and plug connected equipment, and should this ground wire be allowed to serve in addition to the grounding conductor in the cord. What are the dangers/advantages to this?
