Understanding electrical wiring colours in Australia is important for anyone working on electrical systems. This applies to both professional installations and DIY projects. Compliance is critical with safety regulations, including the AS/NZS 3000 standard. This is to ensure all electrical systems are safe and functional. This post will break down the different 240v wire colours Australia uses. We will also explain the purpose of each wire and provide practical tips for safely handling electrical wiring.
The wiring colour codes help identify the purpose of each wire. If you are installing or maintaining electrical systems. Whether you’re installing a simple light switch or working with more complex electrical systems, understanding the live, neutral, and earth colors is vital. The wrong connection can lead to electrical faults, fires, or even personal injury.
Australia has specific wiring color codes regulated by AS/NZS 3000. It is also known as the electrical wiring rules Australia. This guide will help you navigate those standards and ensure your project stays safe and compliant.
In Australia, live, neutral, earth colors indicate the function of the conductor. Here’s a breakdown of the current Australian electrical wiring colours for a typical 240V single-phase system:
These live neutral earth colors must be used in all installations to comply with Australian standards. However, if you’re working on older buildings, you may encounter pre-2000 wiring colors, which differ:
If you’re wondering how to wire a light switch in Australia, it’s important to note that it involves correctly connecting the active, neutral, and earth wires.
For light switch installation, follow these basic steps:
- Turn Off Power: Always shut off the main power before starting any work.
- Connect the Wires: Attach the brown active wire to the switch. The blue neutral wire back to the neutral bar, and the green/yellow earth wire to the switch’s earth terminal.
- Check Compliance: Ensure everything adheres to the current wiring rules.

In more complex electrical setups, such as three-phase systems, the wiring colours change slightly. For Australian three-phase wiring, the color codes are as follows:
Be aware of the European 3 phase colours: Brown (L1), Black (L2), Grey (L3), Blue (Neutral), and Green/Yellow for Earth. Most especially if you are dealing with imported equipment from Europe.
Australia also uses specific colors for emergency systems. These emergency colour codes Australia apply to emergency lights, fire alarms, and other safety-critical circuits. These ensure they are easily distinguishable from regular wiring. These color codes help first responders and technicians identify emergency systems quickly and act appropriately in crises.
Cable with red yellow white wires may be encountered in older or imported installations. These wires can appear in control systems or signaling circuits. But, remember they don’t comply with the standard color code for general wiring in Australia. Ensure that all wiring conforms to the AS/NZS standards to avoid dangerous installations.
If you’ve ever wondered, why are Australian colours green and gold, the answer lies in the nation’s rich natural heritage. These colors represent Australia’s national identity. Green symbolizes the forests. Gold represents the country’s vast mineral resources and sunny environment. This tradition carries over into various sectors. These include sports and branding but do not directly impact electrical wiring standards.
