Where do I find the color code for 3 phase feeder in the NEC. What is the Article Number?

It's another one of those myths that certain colors are required for certain voltages (other than a high leg).
As the others of said and while it may have been a long held trade practice, the NEC is silent on it.
It is certainly true that it is not Code. But it was (color codes in general, not different voltages), so the old-timers suffered through it, even though it is gone now :smile:. From at least 1937 until 1968, color codes were required for various branch circuits, depending on multi-wire or not, mostly.
