Besides 110.15 is there a code reference that I cannot find that dictates how/what color is required for a 277VAC lighting circuit? I am replacing some bad cable underground and a family member/ electrical contractor of 45 years is sure its in the book that it MUST be orange (ungrounded) and grey (grounded).

The NEC doesn't require any color for the ungrounded conductor and the grounded conductor could be white or gray.

Thanks Roger

Thanks Roger

Thanks Roger. Thats what I thought but when my uncle/mentor said it was in the book, I questioned myself. I have looked from front to back in 2002, 2005 and 2008 to be sure but..... I knew I was right. (not often)
