The mandatory colors for power wiring in the National Electrical Code (NEC) are Green, Bare, or Green/Yellow (a yellow stripe or band on green) for the protective ground (PG), and White (or alternatively Gray) for the neutral wire. The wire harness color code is a system that is used to identify the function of each wire in a wire harness. Wire harnesses are used in various industries, including automotive, aerospace, and electronics, to connect electrical devices and components. Using the correct wiring color codes is crucial for identifying line, neutral, and ground wires, which saves time, simplifies maintenance and troubleshooting, and ensures the safety of. Identification & Maintenance: Color-coded wires help technicians quickly identify circuits during installation, troubleshooting, and repair. Error Prevention: Clear differentiation reduces the risk of misconnection, which can lead to equipment damage, performance failures, or safety hazards. IEC published this standard originally as IEC 60446 in 2007. Note:- Different countries have different wiring color codes. It makes it easier and safer to.
