There are several ways in which we can calculate the color that any curcuit number sould, be in three phase work. One of the guys at work as a neat little way to do it. He devides 6 into the curcuit number and what ever color the remainer is is also the color of the curciut. For example 21 devide by 6 has a remainer of 3. We know 3 is black so 21 is also black. Does anyone have any other ways to find the proper color for curcuits?
