What is the last letter on a ground wire?

Explanation:
Ground conductors are identified by color, with green (or green with yellow stripes) used to designate the grounding path. When asked for the last letter on a ground wire, you’re meant to connect to the color name of the insulation. The color name is green, and the last letter of “green” is N. So the last letter on a ground wire is N. Other colors listed aren’t the standard ground color, so their last letters don’t apply to grounding.
