State TWO reasons why the earth pin in a three pin plug is longer than the others

  

Answers


CHARLES
The earth pin is longer than the others because of the following reasons:
i) To open the shutters protecting the live and neutral holes, thus facilitating the insertion of the two pins.
ii) To ensure that earth connection is the first and the last to be made. This prevents/reduces the chances of electric shock.
