Whay is the earth pin longer and thicker than live and neutral pins ?

Text Solution

Verified by Experts

The earth pin is made longer and thicker than live and neutral pins so that it cannot enter into the position of live and neutral pins in the socket. This ensures that earth pin is always connected at the proper place and the user is protected from the possibility of an electric shock.
