In a plug, the live wire (brown) and the neutral wire (blue) are the two wires that form the complete circuit with a household appliance. The earth wire (green and yellow) does not normally form part of the circuit and is included as a safety wire.

What Colour is the live neutral and earth wire?

Plug wiring colours

Wire Colour
Live Brown
Neutral Blue
Earth Yellow and Green





Is live wire and earth wire same?

The live wire is the most dangerous one since it has a high voltage, it should never touch the earth wire (unless the insulation is between them) because this would make a complete circuit from your mains supply to the ground (earth). A shock or fire would be highly likely.

Which wire is live wire?

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.

Which side is live neutral?

The live wire is on the left-hand side while the neutral wire is on the right-hand side. It is fairly simple to connect the wires to the plug socket this is because all plugs today come with connectors. Wiring a plug socket is extremely simple and can be easily done by beginners.

Which one is neutral wire?





white wire

The white wire is the “neutral” wire, it takes any unused electricity and current and sends it back to the breaker panel. The green wire (or it can sometimes be uncolored) wire is the “ground” wire, it will take electricity back to the breaker panel, then outside to a rod that’s buried in the ground.

How do I identify a neutral wire?

Quote from the video:
Quote from Youtube video: You have a neutral if the two controlled wires are white and black look in the box.

How do you find earth wire?

To tell if your home has ground wire, check your outlets. If your outlets have three prongs, then your home has ground wire. If there are only two prongs, then ground wire may not be utilized.

What is earth wire?



(ɜːθ waɪə ) electrical. a wire connecting an appliance to earth.

What color is neutral line?

US AC power circuit wiring color codes



See Table below. 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. Three-phase lines are red, black, and blue.

Which color wire is common?

Red and Black are connected to the switches if the White is used for neutral. The White is often referred to as Common, but the colored wires are also used as hot wires.

Why is earth wire used?



The metallic body of electric appliances is connected to the earth using earth wire so that any leakage of electric current is transferred to the ground. This prevents any electric shock to the user.

What is difference between neutral and earth?

Generally, the neutral point is earthed at the distribution transformer. It helps in keeping the earth and neutral in the same potential which protects the equipment against dangerous voltages in neutral.



Difference Between Earth and Neutral.

Parameter Earth Neutral
Conversion It cannot be turned into the neutral wire. It can be turned into the earth wire.

Can neutral and earth be connected together?

Earth and neutral can be connected together but not at the socket as it is outright dangerous may any wiring fault occur. If neutral wire gets disconnected anywhere, the enclosure of the device will be at live voltage. Neutral and earth are the same thing.

Why neutral is used in electricity?

The neutral wire is used for providing a return path for the flow of current in an AC circuit. The neutral wire carries no current, yet without neutral wire the AC circuit is incomplete. In any electrical circuit, the neutral wire will redirect the path of the electrical current to its source point.

Is earthing required for AC?



Yes it is required. Earthing gives protection to the operator from electricshock.

Why is neutral connected to earth?

Neutral is tied to ground to that the potential danger of a short can be sensed and protected against. I think a better example of the importance is a toaster that is shorting mains to it’s chassis. If it’s grounded the circuit breaker pops every time you plug in the toaster and you either fix it or get a new one.

What are the 3 earthing systems?

The IEC 60364 standard has defined three types of Earthing Systems, namely TT, IT, and TN systems.
