Three-Phase Systems (120/208/240V): Phase 1 is black, Phase 2 is red, and Phase 3 is blue. They make it easy to identify immediately which wires are live, neutral, or grounded (avoiding costly mistakes and hazardous accidents). assigns different colors for 208/120 V and 480/277 V wye configurations; black, red, and blue are used for the 208 V phases, while brown, orange, and yellow identify 480 V phases. The Electrical Appliances (Color Code) Regulations 1969 came into effect on 1 July 1969. This color scheme guarantees the right connections and makes maintenance easier in different installations. The IEC 60446 standard, "Basic and Safety Principles for Man-Machine Interface, Marking, and Identification," establishes global guidelines for identifying electrical equipment terminals, conductors, and wiring colors.
