How To Identify Wiring Circuit Number Colors | EAHQCircuit number colors in a 3 phase panel are really easy to identify once you learn a trick. It’s called the Rule of Six. Rule of six you say? Yes, its actually quite simple. Divide any circuit number by six and you can figure out the color of a wire you need.. And now I’m going to teach you to be a circuit number ninja without using a color coded wiring chart.
