Australian Electrical Colours

By | August 17, 2022



Nearly all of Australia’s electrical wiring is identified by a particular set of colours. This nation-wide system makes it easy for electricians, technicians, and safety inspectors to understand the purpose and potential shocks of any exposed wiring.

Although the main colours are standardised across Australia, it is important to remember that there have been changes throughout the decades. Understanding the designations of the various electrical colours throughout the years is key to Australian safety standards.

The most widely recognised colours used in Australian wiring today are brown, purple, grey, pink, and blue. Brown represents the active wire, which carries the current from the power supply to the consumer. Conversely, blue indicates the neutral wire, which works to complete the circuit and returns the current to the power source. Grey highlights the Earth wire. In the event of a malfunction, it is designed to protect users from electric shocks. Finally, purple and pink highlight other cables for specialised installations such as doorbells and smoke alarms.

These colours are part of an integrated system that is both intuitive and highly effective. Regardless of your level of experience, understanding the roles of each colour is essential for Australian safety regulations. As such, it is important to be aware of any changes or updates to the layout. This will help ensure that whether you are a qualified electrician or a DIY enthusiast, you always comply with the relevant safety standards.
