Why Is the Earth Pin of An Electric Plug Longer Than the Other Two Pins?
The Function of Earth Pin: A 3-pin plug has a live, neutral, and earth pin. The live and neutral pins have the same thickness and length. But the earth pin is a little longer and thicker. In a properly earthed system, when we connect the 3-pin plug to a 3-pinhole socket, the metallic part of the appliance gets a direct connection to the earth via the earth pin. When there is a current leakage, the earth pin helps to divert the leakage current from the appliance to the ground. Thus, we can avoid electrocution by touching the metallic part. Modern sockets possess a safety shuttle in the earth pinhole. When we push the earth pin down, the safety shuttle for the live and neutral pinholes will open. Three Pin Plug Significant factors: The earth pin is useless if the building is not earthed. The earth pin helps to connect appliances to the ground. It helps to open the safety shuttle of modern sockets for the live and neutral pinholes of the socket. Why is the E
