What Are The New 3 Phase Colours?

It is no secret that the new colour coding for electrical wiring for three-phase systems has recently been changed. These changes have caused many to question what these new colours are and why they have been implemented. Understanding what these colours are and why they’re being used can help ensure that your electrical wiring project goes as smoothly as possible.

The new three-phase colour coding standard consists of five wires, each with its own distinct colour. The first colour is black, which is the hot wire from the power source. This wire carries the power to the load. The second colour is red, which is a hot wire that is switched off and on. The third colour is blue, which is also known as a neutral wire and carries the current back to the source. The fourth colour is yellow, which also carries the current back to the source but supplies a lower voltage than the other wires. Finally, the fifth colour is green, which is a ground wire that provides a safe return path to the power source.

Understanding these new colour codes is essential to any electrical wiring project. Knowing the meanings behind each colour, as well as how they interact with one another, is critical to ensuring that you are wiring correctly and safely. For this reason, it is important to know what the new three-phase colour codes are and why they’re being implemented in order to avoid potentially dangerous situations. With the new standards now in place, electricians are able to work on any three-phase system in a safe and efficient manner.
