Why is the third pin necessary?

The 3-pin plugs are designed so that electricity can be supplied to electrical appliances safely. Each wire has its own specified color, as shown above and each pin must be correctly connected to the three wires in the electrical cable. This type plug is commonly used for heavy appliances such as the air-conditioners.

What is the purpose of third big pin in 3-pin power top?

When we insert a 3-pin plugin into a 3-pin socket, the earth pin is the first to make a contact with the socket as compared to the Live and Neutral Pins. The earth pin is the last to disconnect from the socket when removing the plug from the socket. i.e. Line and Neutral disconnect first and then the earth pin.

Why is the top pin of a three pin plug made longer than the other two pins?

Among these three pins (live, neutral and earth), the earth pin is made longer and thicker than the other two pins, so that when we insert the plug into the socket, the earth pin comes into contact with the power supply before the other two pins, this is because if any unwanted charges are there then they will be …

Why is one of the 3-pin of a 3-pin plug is longest and thickest?

The earth pin is long so that the earth connection is made first. This ensures the safety of the user because if the appliance is defective, the fuse will blow off. The earth pin is made thicker so that even by mistake it cannot be inserted into the hole for the live or neutral connection of the socket.

Can I remove the third prong on a plug?

The third prong on an electrical cord is the ground plug. It is not safe to cut the ground prong. Ever. Here’s why: A ground prong creates an emergency path for electricity to travel through if a short circuit or fault happens within the device.

What is the role of each of the three pins in a power plug?

A 3 pin plug consists of three pins (hence the name). Each pin must be correctly connected to the three wires in the electrical cable. This is the route the electric current takes when it exits an appliance; it is for this reason the neutral wire has a voltage close to zero.

Why does the pin have split ends?

(b) The pins are splitted at the end to provide spring action so that they fit in the socket holes tightly.

Why do some plugs have no earth?

Some appliances, such as vacuum cleaners and electric drills, do not have an earth wire. This is because they have plastic casings, or they have been designed so that the live wire cannot touch the casing. As a result, the casing cannot give an electric shock, even if the wires inside become loose.

How do you remove a plug prong from a socket?

Turn off the circuit breaker to the outlet. Test it with a circuit tester to make sure the power is off. Inspect the broken prong to see how deeply it is embedded in the plug. If it is sticking out enough, grab it with a pair of needle nose pliers and pull it straight out.
