Wiring color code
IEC 60446 is equivalent to HD 308 S2, DIN VDE 0293-308, BS 7671 (since 2004), GOST R 50462 and other national norms.
- International: Regulated by the International Electrotechnical Commission (IEC). The countries that follow the IEC are most of European countries, the United Kingdom, and some other countries (Argentina, China, Hong Kong, Singapore, Russia, Ukraine, Belarus, Kazakhstan).
- United States: Regulated by National Electrical Code (NEC). NEC specifies that neutral is white or gray and ground is green, green with yellow stripes, or bare copper. Any others color except the colors mentioned above can be used for other power line cables. There is a local practice about specific colors we should use. Local practice are divided again into two groups: 120/208/240 V a.c. and 277/480 V a.c.
- Canada: Regulated by the Canadian Electric Code (CEC). The protective earth or ground uses green color or green with yellow stripes. The neutral cable color is white. For the line wire colors are quite similar to US wiring color codes. The active wiring color codes are separated into two groups: normal and isolated systems.
- Brazil: Regulated by the Associação Brasileira de Normas Técnicas (ABNT). Any color can be used for active line except blue, green, yellow, green with yellow stripes.
- Australia and New Zealand: Regulated by AS/NZS 3000:2018 3.8.1, table 3.4. Any color can be used for hot wire except yellow, blue, black, green, and green with yellow stripes. The recommendation is for single-phase line red or brown and switched line white, for multi-phase line red, white, blue, and neutral black or blue.
