Hi, my name is Andres, I m a student in electromechanical engineering, I have a doubt about the color code in voltage system, I know that 120/208/240V is: phase A= black, phase B=red, phase C= blue and nuetral=white, and 277/480V is: phase A= brown, phase B=orange, phase C=yellow and nuetral=grey, I also know about the high leg delta marking.

My doubt is about systems that work at  230/400V what color code is it? for the moment I haven't found anything in the NEC Handbook 2017.
