Hint: Overcrowded terminals
I counted six equipment grounding conductors (EGCs) and bonding jumpers jammed into this lug designed for only two conductors. Jamming six conductors into terminals designed for no more than two conductors is a violation of Sec. 110.14(A). Terminals for more than one conductor must be identified for such use. Using equipment in ways that contradict the listing or labeling instructions is a violation of Sec. 110.3(B). On a positive note, the installer did take the time to remove the paint from the enclosure where the lug was bolted on. This was a great job in complying with Sec. 250.12, which requires nonconductive coatings like paint, lacquer, and enamel to be removed from contact surfaces to ensure good electrical continuity. As for the orange tape installed on the green wires, there are no Code rules prohibiting the use of marking tape on EGCs or bonding jumpers. Section 250.119 requires insulated or individually covered EGCs to have a continuous outer finish that is either green or green with yellow stripes. In this case, the continuous green outer finish has orange marking tape installed over it. I don’t see any real-world problems here.
