The NEC National Electrical Code states for 240 volt circuits there should be 2 colors but not white or neutral gray for single phase. If there were 3 transformers on a pole connected wye on the primary, and delta on the secondary, and you opened one of the cut-outs, you'd still have 3 phase power available on the secondary.

I'm curious to see what sort of "color code" different regions of the country use. To make it easier to find specific information related to an exam question, you’re going to break down each article within the code by:. In the Detroit area we use 1/8 phase conductors are black, red, blue, the neutral is white and ground is green.

With the exception of very short momentary inrush currents, all 400-amp services are strictly limited to a maximum. However the code specifies that conductors by phase and voltage shall be identified. We do use numbered cables, and cable labels, but we sleeve the ends as we terminate to the colour code when appropriate.
