What color phasing tape should be used for a three-phase 575V system?

Answer 1

The industry standard for low voltage (120-208V) conductors is: A phase: black B phase: red C phase: blue As you look at a three phase panel, the phases go left to right (the same way we read). Therefore, the supply conductors should be black, red, blue, left to right. (A phase is not typically marked as the wire insulation is already black in color.) The branch circuit conductors should always be the same color of their phase supply conductor. This is a critical industry standard although it is not required by the National Electrical Code. <><><>

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.

Before you do any work yourself,

on electrical circuits, equipment or appliances,

always use a test meter to ensure the circuit is, in fact, de-energized.
