Per 250.119, an equipment grounding conductor may be identified by which of the following?
a.White insulation
b.Gray insulation
c.Blue insulation
d.Green, green with yellow stripe, or bare
Explanation
Section 250.119 permits equipment grounding conductors to be green, green with one or more yellow stripes, or bare. White and gray are reserved for grounded (neutral) conductors, and blue is used as an ungrounded conductor color.
