600/347 color code

[pipe_bender]

Hey gang looking at some engineered prints and is it OK to use Red / Black / Blue = Phase A / Phase B / Phase C for a 600/347 system if there is already a 208 that uses Black / Red / Blue = Phase A / Phase B / Phase C?
There is a 480V system that has standard BOY.
There would be a plaque and voltage marking stickers on the pipes.
Thanks everyone.

210.5 requires ungrounded conductors of different system in premise wiring to be uniquely identified at all terminations, connections and splice points but does not require that to be done by color.
Marking, taping, tagging or other approved means may be used.
There are similar requirements in 200.6 for grounded conductors.'
Marking of the conduit would not seemingly meet that requirement sinc eit specifically says each conductor,

Thank you, I *think* the engineer was suggesting is this color scheme makes them unique, I was not sure why the order.
On the 600V system the phase colors for phases A and B are swapped from the 208.
600V phase A = red.
208 phase A = black.
I don't know how I would ever tell them apart, but its technically not the same color code for voltage and phase.

I don't know how I would ever tell them apart, but its technically not the same color code for voltage and phase.

If there is more than voltage system, 210.5(C) would not permit that. Each conductor must be identified as to phase and voltage system.

I don't think reversing the colors for a different voltage would qualify and would cause more confusion.

You have Brown-orange -yellow for the 480 and Black-Red-Blue for the 208. For the 600v I would use violet, pink, gold.

or on the 600v use violet for all 3 phases 1tape phase A, 2 tapes phase B and 3 tapes phase 3
