In Australia, electricity is supplied at 240V and 50Hz. The Active wire (high potential) is coloured brown (used to be red). The Neutral wire (low potential) is coloured blue (used to be black). The Earth wire is striped green and yellow (used to be only green). Circuit breakers and Fuses protect against too much current.
What color is the Live Wire in Australia?
Within Australia the live wire is brown, the neutral wire is blue and the earth wire is green and yellow. This may not be the same for every electrical system as the wire colour codes have altered throughout the years.

Can white wire be used in 240V?
It's perfectly legit to use /2 cable (black-white) to hook up a 240V-only load (hot-hot-ground). However, you MUST re-mark the white wire with tape or paint to indicate that it is a hot, so this doesn't happen.
What is the Australian Electrical Wiring Colours Coding Standard?
The wiring colours coding standard was initially made in 1894 and were a voluntary code, which only members of an authorised organisation could use. However, in 2000 the codes were made an officially regulated code. Australian electrical wiring colour codes have evolved over the last 100 years with the inclusion of colour coding.
How to Use the Wire Colour Code Standard
The following sections are not technical and are meant only to provide basic information for regular residential and commercial customers.
What Does Each Wire Colour Mean?
Colour codes have been developed with care for your safety and endorsed by the Australian Standards Association (ASA).
Original Purpose of the Electrical Wiring Colour Codes
The use of different electrical wire colour codes for the different conductors was originally to indicate their "lifespan." For example, the colour yellow meant a conductor that would reach a specified wire length and then be connected to an earth wire.
Wire Colour Coding and Your Electrical System
The Australian electrical code, EJ8, is a good starting point for maintaining a sound electrical system. It is easy to follow and easy to remember. It is important to remember that as the standards become more demanding and more people install electrical systems, more training and certification will be required.
What color is the neutral wire?
You must ensure that there is no power source connected with the live wire before working on the wiring. The neutral wire colour is blue.
What is the difference between blue and brown wires?
The blue wire, also referred to as the neutral wire, has the function of transferring electricity away from the appliance. The brown wire, otherwise known as the live wire, transfers electricity to the appliance. The combination of these wires is referred to as a circuit. You should be aware that some properties have old-style wiring, which should be regularly checked by an electrician to ensure that it remains in good working order. The need for replacement will be entirely dependent on the safety of the wiring.
How to tell if a two phase or three phase?
You can identify either the two or three-phase connection by counting the wires connected with the electrical service panel. A single-phase connection will feature dual black or red live wiring and blue neutral wiring. There is a voltage difference of 230V between the wires. Either three or four wires will be connected to an electrical service ...
What does brown wire mean?
It is important that you don’t make the mistake of confusing the natural blue and green/yellow earth connection when referring to the electrical system. Brown = Live. As previously mentioned, the brown wire has the function of carrying electricity to the appliance.

The combination of these wires is referred to as a circuit. You should be aware that some properties have old-style wiring, which should be regularly checked by an electrician to ensure that it remains in good working order. The need for replacement will be entirely dependent on the safety of the wiring.
How many wires are in a three phase system?
Either three or four wires will be connected to an electrical service panel functioning via the three-phase system. This will feature three live wires of either a black, red, brown or grey colour and a separate blue wire. There will typically be a 400V separation between the two live wires.
What is the green and yellow wire?
The green and yellow wire is also referred to as the earth wire and has a key safety function. Electricity being transferred around any property will always take the path of least resistance to the earth.
What are the Wiring Colour Codes with Single and Three Phase Wiring?
Single phase wiring is where two wires connect and allows an easy balance of electrical currents and loads across networks. Three phase wiring consists of three to four wires that provide a stronger electrical current.
Are the Wiring Colour Codes the Same Everywhere?
Each country will have its own electrical code for the colour of the wires. Within Australia the live wire is brown, the neutral wire is blue and the earth wire is green and yellow. This may not be the same for every electrical system as the wire colour codes have altered throughout the years.
