Hello friends, you are once again welcome to our website, friends, in today’s blog post, we will talk about a very important topic, that is why the above Pin is thick and long in the three Pin Plugs. It is made, what is the reason that this pin is made thick and long, so let’s see it?
Why is the earth pin thick and long?
So, friends who are Three Pin Plugs, there are mainly 3 reasons behind making the above Pin thick and long, we see all the three reasons one by one?
Reason no. 1
So the first reason for this is that we mostly use those 3 Pin Plug Tops with those devices which have more Power Consumption or the devices which have body metal such as – Refrigerator, Electric Iron. , Electric Geyser, Immersion Rod, Air Conditioner, or Electric Kettle So 3 Pin Plug is used with all these devices?
Now, these 3 Pin Plugs have 3 types of Pins on them, the first pin is for Phase wire and the second pin is for Neutral wire and the third pin which is thick and long is for Earthing?
So friends, as we know that any device needs 2 wires to run, the first phase and the second neutral, and the third pin which is earthing is connected to the body of the device, now friends we Why do we do earthing as soon as we do earth to protect the human body from electric shock, yes?
Now suppose that I am driving a motor and some fault has happened inside that motor, as if the phase wire inside that motor has been cut from somewhere or the mouse has cut it and touched the body of the motor. If this is happening then in this condition current will start coming in the whole body of the motor and in this condition if a human comes and touches that motor then that human can get an electric shock?
So keeping this in mind, the top pin in the plug is made long so that if there is a fault in any motor or the wire inside the motor is broken or there is also a touch, then when we put the plug in the socket, then our The earth pin in the plug should already be earthed, that is, the first pin should be installed in the earth terminal inside the socket, and then the pin with phase and neutral should be installed in the socket?
What will happen with this is that if the phase wire is also touching the motor body then the earth wire or pin will already be earthed and the motor body will already be ground and later will be supplied inside the motor that is why the earth pin is made long. Is it for the safety of the human body?

Reason No. 2
Now let’s talk about Reason no. 2 The reason why the pin of this plug is made thick is that as most people know why all the three pins are given inside the plug as below for both the phase of the pin and neutral and For the top thick Pin Earth?
Now friends, if there is such a person who does not know about it, such as a small child, then perhaps there will be no idea about the pins of these plugs? Now, what will happen if all the three pins of the plug are made of one size?
Now the top pin in the plug is connected to the earth’s body, now in this condition, if a child will install this plug, then if all the three pins are of the same size, then if a child will put the plugin the socket, now he will by mistake. Do not put the earth pin in the terminal with the socket’s phase?
If accidentally put in the phase terminal, then the earth pin is connected in the plug to the body of the instrument, and due to which current will start coming in the whole body and if someone touches it then he can get an electric shock?
Keeping this thing in mind, the upper pin in the plug is made thick, so that the proper marking i.e. the earth pin in the plug should go to the earth terminal inside the socket and not to other terminals like the phase ones. And in the terminals with neutral?
Reason No. 3
Now friends talk about the third reason, due to which the pin of the plug is made fat?
So the reason for making the pin of the plug thick is Resistance Yes? As we know that if we increase the thickness of a conductor, that is, the area of cross-section, then the resistance of that conductor decreases?
Similarly, the plug which has the earth pin is made thick so that the resistance of the earth pin can be minimized and good earthing can be provided? Friends, a good earthing is said to have the least resistance, that’s why that pin is made thick?
So, friends, these were the 3 reasons why the upper pin in the plug is made thick and long?
