What is the difference between earth wire and active wire?
For example, active wires are also known as hot wires. In a three phase system they are referred to as phase 1, 2, or 3 wires, or live 1, 2 or 3 wires. Meanwhile, an earth wire can also be referred to as a ground wire. That’s some similar phrasing but it certainly makes it tricky for an electrical novice.

What colour wires are 3 Phase Australia?
Australian engineers use red, white and blue for their live wire colours. The specific difference that is unique to Australia is the white L2 line. However, it is also permissible in Australia to use European colours in some circumstances according to AS 3000.
Can I tie the neutral and ground together?
No, the neutral and ground should never be wired together. This is wrong, and potentially dangerous. When you plug in something in the outlet, the neutral will be live, as it closes the circuit. If the ground is wired to the neutral, the ground of the applicance will also be live.
Why are wires color coded?
The purpose of wiring colour codes is to enable an electrician or anyone else who has cause to go near the wiring in a building and immediately tell which wire is ...
What color wires are used for TV?
Just because a wire is a particular colour, that doesn’t always mean that the colour code applies. For example, many TV aerial cables are coloured brown, which indicates a live wire under the wiring colour codes. However, TV aerials do not carry any voltage and aren’t subject to the same safety considerations as live wires carrying electricity to appliances are. Similarly, you will find plenty of black cables around the average home. Many of these carry electricity from your mains supply to your appliances, but they have the same colour as the neutral wires.
Do you have to rewire a house if you have wire color codes?
Just because you have the colour codes to refer to doesn’t mean you should rewire your home.
Do color codes change over time?
It is also important to note that these colour codes have changed over time, and will presumably change again in the future. If you are looking at the wiring for an appliance or property that is decades old, you need to consider that the wiring might reflect previous colour codes.
Do you need to know the color of your wires?
Whether you are moving into a new property or you need to do some DIY involving your home electrics, you need to know your wire colour codes. If this is your first time dealing with electrics or wiring, it’s critical that you find out exactly what you are dealing with before you go anywhere near live wires.
Do all electrical cables have the same color code?
No. There are also different colour codes for single-phase and multiphase systems. However, since the introduction of the latest wiring colour codes, both fixed electrical cables and mains-powered cables use the same colour code scheme.
Electrical Wires' Primary Purpose
Assume again if you think there's only one wire delivering power to and from your outlets and appliances. Each wire has a distinct purpose. Colour labelling allows your electrician to quickly identify each function, which aids in detecting any faults.
Electrical Wiring Standards in Australia in 2021
Since the adoption of the AS 3000 in 2018, Australia's wiring has better reflected worldwide standards. Electrical wire colours in Australia mirror those in Europe and the United Kingdom, allowing more items to be effortlessly integrated into international circuits.

Where is the neutral wire located?
The neutral wire transfers electricity away from the appliance to avoid overloading. It is located at the end of the circuit for connection after the electricity has flowed around the live and earth wires. It is highly unlikely that you will have an electric shock on contact with a blue wire.
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 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.
