The earth wire is striped green and yellow (used to be only green). Show activity on this post. Use a multimeter. It's almost certain the green/yellow is ground.
Which is live black or red?
The protective ground is green or green with yellow stripe. The neutral is white, the hot (live or active) single phase wires are black , and red in the case of a second active.
Is the black wire live or neutral?
Any circuit's black wire should be considered live at all times. These wires are often used as a switch leg that transfers power to switches and outlets in all circuits. Black wires are never used for a ground or neutral wire and are meant to be used as the power feed for a switch or an outlet.
Is the red wire the same as black?
Black wires are hot wires that run to the electrical outlet from the switch. Red wires are hot wires common in a 240-volt outlet or when a wall switch controls the outlet. Blue and yellow wires are hot wires for ceiling fans and three- or four-way switches. White or gray electrical wires are neutral wires.

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.

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?

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 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.
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.
What is the combination of wires called?
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.
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.
