Question

Why the earth pin have longer and thicker than live and neutral pins?

Answer 1

Answer:

TO PROTECT US FROM GETTING AN ELECTRIC SHOCK

EXPLANATION:-

The earth pin is longer so that the appliance is first earthed. The earth pin is thicker, so, that even by mistake it cannot enter into the live hole of the socket. In case, the live wire happens to touch the metal casing of the appliance due to short circuit, heavy current flows through the thicker earth pin hence avoiding any electronic shock.
