Hi,
Did a quick search on the forum and could not find a topic on this (there probably is). I did see a post on control wiring today but could not find an answer.
I see standard industry guidelines for the different wiring colors for ungrounded conductors throughout articles on the web. And they mention this is per NEC but they do not reference a section of the code. Are the colors of ungrounded conductors part of the code?
I know county's and cities might have there own compliance for color coding but I am wondering if this come from code...
The city requires brown-yellow-purple, but a product we are purchasing has standard industry colors for 480/277V which is brown-orange-yellow. And I see the standard industry colors all over the articles I am finding.
Thanks you
