Standard Colors for Electrical Distribution Box Protection

Standard Colors for Electrical Distribution Box Protection

If a circuit includes a neutral or midpoint conductor, then it should be identified by a blue colour (preferably light blue ). Light blue is the colour used to identify intrinsically safe conductors, and must not be used for any other type of conductor. The preferred colours for AC phase conductors are: • L1: Brown 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 international standard IEC 60446 Basic and safety principles for man-machine interface, marking and identification - Identification of equipment terminals, conductor terminations and conductors was a standard published by the International Electrotechnical Commission (IEC) that defined basic. Many countries, including the UK (BS-7671), China, Russia, Hong Kong, Singapore, Ukraine, Belarus, Kazakhstan, Turkey, Israel, South Africa, Argentina, Malaysia, Saudi Arabia (KSA), and the UAE, have adopted the IEC wiring color codes.
