Multiphase wiring is required for carrying larger amounts of electricity and is considered more stable, than single phase. Electrical Wire Color Codes. Non-metallic (or NM) 120-volt and 240-volt electrical cable come in two main parts: the outer plastic sheathing (or jacket) and the inner, color-coded wires.The sheathing binds the inner wires together, and its outer markings indicate the number of wires and size of wire (gauge) within the sheathing. NOTE- The Installation colour codes are quite flexible – so caution is needed – actives/phases can be almost any colour – and are sometimes the same colour. In case of a three phase power supply, the combination of Red, Yellow and Blue are used for the active line power conductors, Black color for neutral conductor and Green or Green – Yellow for protective ground.
