taping 480 3 phase

[joshshop]

I had a fellow electrician tape a 480 three phase with B O Y colors inside the peckerhead on a motor then he taped the split bolts with cambrike, rubber, then gray tape. I suggested the gray tape was a code violation but he thought since he had B O Y taped the wires then the gray taped didnt matter. Cant find anything in the code book on this.

There are no rules on the which colors are used. But if the facility is served with more than on premises wiring system, each voltage system must be identified by line and phase at each branch circuit panelboard.

210.5(C) - there is a significant change from the 05 to 08, this is the 08:
(C) Ungrounded Conductors. Where the premises wiring system has branch circuits supplied from more than one nominal voltage system, each ungrounded conductor of a branch circuit shall be identified by phase or line and system at all termination, connection, and splice points. The means of identification shall be permitted to be by separate color coding, marking tape, tagging, or other approved means. The method utilized for conductors originating within each branch-circuit panelboard or similar branch-circuit distribution equipment shall be documented in a manner that is readily available or shall be permanently posted at each branch-circuit panelboard or similar branch-circuit distribution equipment.


I really dislike split bolts. They are more expensive than the T&B motor stub boots I use, and way slower to install.
