why the earth terminal in three pin top is longer than rest
of the two terminal and of bigger size?

Answer Posted / sunil ulange hit nidasohi

Because Current always take low resistance path, i.e
Resistance is inversely propotional to Area,

means higher the fault current, lower the resistance,
Higher the conducting area i.e Earth terminal area is higher
than normal pins

R = ql/A, Resistance increases, area decreases
