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.
