Answer Posted / mahendra
earth hole size is biggest in plug point because, when we
took out the plug from socket the phase & neutral terminals
of socket comes first then the earth contact. Due to safty
purpose Earth contact should be disconnect at the last
moment this prevent any damage to human being and equipment
as well for any abnormal conditions. Another reason for
that is to keeping large contact area for earth because in
fault like earth & short circuit a large current
approximately 6 times flows through circuit.
