What colors do you guys tape conductors for 240V 3PH with no center tap?
I would go with Black, Red, Blue.
If corner grounded, the grounded conductor must be white or gray. Most would probably go with black, red and white, but could easily be confused with a 120/240 single phase system, so is probably a good idea to have additional signage indicating what is there. I think 2014 has requirements to mark equipment with the nominal system voltage, went to a code changes class last weekend and seems to recall that coming up, probably in art 110, but possibly 408?My response is based on this being a 3 phase, 3 wire system.
