Differences in Wire Colors Between England and North America

Wire colors are not standardized and may vary from country to country.  This article explains the differences between wire colors found in the U.S. and wire colors in England.

Q: I’m training to be an Electrician here in England. I have looked everywhere for the information and couldn’t find it, but I was wondering, and it’s a silly question.

We have Brown for Live, Blue for Neutral, and Green/Yellow for Earth (cpc). I was wondering what the color coding is please, in the USA?

A: Here in the North American system, Black, Red, (and Blue in 3-phase systems) are hot wires, and White is neutral. Green and/or Bare wires are ground.
