Answer Posted / a.rafeeq raja
As Leakage current need to flow through the Earth Wire
the resisitance should be as low compared to that of the
phase and neutral wires.Besides,The resistance of the
conductor is inversely proportional to the cross sectional
area of the conductor .Hence bigger cross sectonal area
reduces the resistance and provides a easy path for the
current flow.So the Earth Pin is always bigger than the
other two pins in a 3pin plug.

generally in LT and MV motors we are using 3.5Coresx16,25,35,50 etc cable for supply.although motors is earthed at two point and having all protection.then why we are using that 1/2 core for earthing the motors.while in HT cable we are using only 3core cable for motor supply.generally lt and mv motors are delta connected and ht motors having star connection.whethere it is having any relation with winding connection( star or delta).all motors i am talking about are dol only.can anybody solve my confusion.thanks...
