electrical wire colours south africa

Electrical wiring is an essential part of any building, so it is important to be aware of the different colour codes used in South Africa. By understanding the meaning of each colour, you can ensure the safety of your electrical system and guarantee compliance with the National Electrical Code.

In South Africa, the colour codes are based on the European system, which has been adopted by many countries in the region. The colours used for the various wires signify their purpose, safety ratings, voltages and amperage. The most common wires found in new installations are brown, blue, yellow and green.

Brown wires are used for the live wire or phase. This carries power from the main power source to the switches and outlets. Blue wires are used for neutral, or return, which carries power back to the source. Green wires are used to indicate grounding and yellow wires are generally used for intermediate higher voltage lines.

The colours for wiring have a specific purpose, so it is important to follow them in order to ensure safety throughout your electrical system. It is recommended that anyone unfamiliar with the correct use of colours should consult a professional electrician or seek advice from the local Electrical Safety Authority. Following appropriate colour codes is essential to maintaining the safety of your electrical system.
