Everything About Electrical Wiring Colours and Coding Standards

Australian wire colour codes are the standard for identifying conductors in electrical wiring. These wire colour codes ensure safety and avoid confusion in residential and commercial wiring systems. 

An electrical wiring company shares that, according to current Australian Standards, the following wire colours are used in most electrical installations - brown, blue, green and yellow. 

Australian Wiring Colour Coding Standards Means

The wiring colour coding standard was invited to recognise the purpose of using the wire. However, it became an officially regulated code. Since then, the Australian electrical wiring colour code has not changed. 

This allows users to instantly understand the wiring in their home or business. The Australian residential wiring standard is AV1. These wiring standards do not delve into insulation or connection issues but are limited to the basic wiring in a home. 

According to the electrical wiring contractors in Brisbane, typically, there are only three wires in the wiring system that are used for residence: live, underground and ether. Each wire must be installed at least 1 metre from the ground wire. Outside the house, the live wire is located on the roof and carries electricity. 

Inside the house, three wires can be connected to a socket: two internal (power) wires and a neutral (earth) wire. The ground wire in Australian homes is a type of electrical conductor called a ground wire. It is the primary wire with a negative terminal that connects the homeowner to the Australian electrical system.

Meaning of Each Colour of Wire

The colour codes have been approved by the Australian Standards Association (ASA) and are designed with safety in mind. The colours listed below correspond to the current standard. Do not match the colour of the wires in your home and be sure to consult an electrician.

Energised Wires

Brown is typically used as the colour for live conductors. Red is also used for live wires that generate voltage when plugged into an outlet but are not grounded. The colour used in your home depends on when it was built. Never do the wiring yourself! Call electricians to take a look.

Signal Wires

According to an electrical wiring company near Brisbane, signal lines connect points to the primary network. If the system is grounded, it must also be connected to the primary network. This is why the colour code is different from other wiring systems. Designers make sure the wiring system has the signal line colour code printed on it in a colour that is visible to workers and occupants.

Ground and Neutral Wires

Ground wires are almost always green or green-yellow. Ground wires are almost always green or green-yellow and are either coloured the same colour or connected in parallel with another neutral wire. Neutral wires usually have studs extending from both ends, one on each bus bar. When installed underground, neutral and ground wires are usually grounded.
