Why is the earth pin thicker and longer than live and neutral pins?
The thickness of the earth pin makes sure that the earthing does not enter the live hole of the socket. Thus, in case a neutral and live wire is in contact with the metallic cover of an appliance due to an event of short circuit, the heavy current will flow through that earth pin to avoid any sort of accident.
What does the neutral pin do?
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. and connected to the earth pin. This is used when the appliance has a metal casing to take any current away if the live wire comes in contact with the casing.
Why is the plug hot in the outlet?
Sometimes homeowners come across outlets that are too hot to touch even when nothing is plugged into them. A hot outlet indicates an issue that requires immediate attention. It can happen due to loose or corroded wires, wetness, or unplugging something from an overloaded outlet, and may even result in a fire.
How is the earth pin different from other pin?
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 the earthing pin so big?
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.
What are the connections present inside the three pin plug?
For a 3-pin plug, there are typically 3 different wires which need to be connected to the back of the plug. The three wires are the earth wire, live wire, and the neutral wire. These 3 wires come in a cable with different colors, which is done to distinguish between the three wires.
Why the earth pin is not the same size as the other 2 pins?
First reason, to prevent the wrong way to operate a 3-pin plug and connected electrical machine for the safety purpose. In short, The earth pin is bigger and it can not be inserted in the live or neutral slot of the socket even by mistake. Second reason for thicker pin is that the law of resistance.
Why is earth pin made thicker than live and neutral?
Let’s take the example of an Electric iron again. A. When the plug is inserted in socket, earth pin makes connection to the earth hole of the socket prior to live and neutral. Thus the earth connection is made before the current carrying contacts of the plug become live to prevent us from any kind of electric shock.
Why is the earth pin longer in a 3 pin plug?
In this case, the longer earth pin help to open the shutters for Line and Neutral pins i.e. without longer earth pin, The shutters for Line and Neutral remains closed for better safety. Now we know another reason that’s is why the earth pin on a 3-pin plug is bigger other than Neutral and Live pins.
How is earth pin attached to live hole?
Due to the fact that earth pin is directly attached anywhere on the metallic body, if earth pin is inserted in the live hole, current will flow from the live wire of socket to the earth pin of Iron to the metallic part of the iron’s body.
