The 3 wires are live, neutral and earth. The current travels along the live and neutral because 2 wires are needed for the the current to flow, while the earth is a separate safety wire that normally carries no current, until a fault occurs.

The neutral wire completes the circuit and carries the current back to the power source. It provides a path for the electricity to return safely to the earth or ground. In a 3 pin plug, the neutral wire is usually color-coded as blue.

What is the blue wire for in a three pin plug?
The blue wire in a three-pin plug is typically the neutral wire. It completes the circuit, allowing the electrical current to return to the power source safely.
Why you use neutral pin in three pin plug?
In North America the neutral pin is used to complete the circuit. One pin is "hot", one pin is neutral and the last pin is ground.
Why you use three pin plug insted of two pin?
A three-pin plug provides an additional ground connection for safety. This grounding pin helps to prevent electric shocks by providing a path for excess current to flow safely to the ground. It also helps to protect against electrical fires and equipment damage.
What is significance of red black and green wire in three pin plug?
The significance of the red, black, and green wires in a three-pin plug typically corresponds to their functionality. The red wire is usually the live wire, the black wire is the neutral wire, and the green wire is the earth wire. These colors help to identify and properly connect the wires for safe and correct electrical wiring.
Can you plug a 2 prong plug with the same size slots into a 2 prong plug with one slot larger?
Yes, the larger slot is a polarity slot that is supposed to connect the plug in device to the neutral wire. If the device is a lamp it would make the shell of the lamp the neutral wire connection and the center pin the "hot". If the two wire plug has a moulded plug on it, look for a tracer on the devices power cord. It will be a raised rib or a white tracer on the conductor that is the neutral. Position the two blade plug into the receptacle with the identified conductor into the larger slot, this will give you the proper polarity configuration that the manufacturer recommends. New plugs (caps) today all have a ground pin connected to them and can only connect to the receptacle in one position.
Which wire is not present in a 2 pin plug?
In a 2-pin plug, the wire that is not present is the grounding wire. This type of plug only has two prongs for the live and neutral wires, unlike a 3-pin plug that includes a grounding wire for added safety.
How do you connect the 3 pin plug?
One pin for phase other pin for neutral and third one is for earth/ground wire. In India the right pin is for phase, left pin is for neutral and pin on top side is for ground wire. This third top side pin is slightly bigger and longer compared to phase and neutral pins.
What is the blue wire for in a three pin plug?
The blue wire in a three-pin plug is typically the neutral wire. It completes the circuit, allowing the electrical current to return to the power source safely.

A three-pin plug provides an additional ground connection for safety. This grounding pin helps to prevent electric shocks by providing a path for excess current to flow safely to the ground. It also helps to protect against electrical fires and equipment damage.
What is the purpose of a wire?
it is the brown wire in a three pin plug
When use a 3-pin mains plug what is the biggest pin for?
The biggest pin on a 3-pin mains plug is usually the earth pin, which is used for grounding the appliance to prevent electric shock and ensure electrical safety.
What is significance of red black and green wire in three pin plug?
The significance of the red, black, and green wires in a three-pin plug typically corresponds to their functionality. The red wire is usually the live wire, the black wire is the neutral wire, and the green wire is the earth wire. These colors help to identify and properly connect the wires for safe and correct electrical wiring.
Color code in 3 pin electric plug in India?
Green with Yellow Stripe Wire - Earth Wire (E) Blue Wire - Neutral Wire (N) Brown Wire - Live Wire (L) When you look at the plug with the terminals facing towards you: /\ / \ / E \ / \ / \ / L N \ ------------------

What is the function of the live wire in a 3 pin plug?
The live wire in a 3-pin plug carries the electrical current from the power source to the appliance or device being used. It is typically color-coded as brown in the UK and red or black in other regions to help differentiate it from the neutral and grounding wires. It is important to handle the live wire with caution as it carries the risk of electric shock.
How do you wire a three prong plug that has a horizontal prong?
To wire a three-prong plug with a horizontal prong, the green/yellow wire connects to the ground pin, the white wire connects to the neutral pin, and the black or red wire connects to the hot pin. Make sure to secure the wires properly and use the correct tools to avoid any electrical hazards.
