Answer / kishore kumar

because R=Pl/a area of the conductor increases resistance
value dicreases .so high lekage current flows it thats why
the area of the earthing pin is big compare yhe phase and
neutral pins.

Answer / siva24381

Because Current flow in the conductor is inversely
proportional to the conductor diameter.so if any short
circuits occures in the system first high currents bypassed
in the Earthing terminal.

Answer / vaibhav kumar

actually in first answer he tried to write directly proportional .....

logic is correct

but as the diameter increases rate of current flow also increases

Answer / j.karthik

I think Mr.Kishore kumar said answer is correct.i.e. R=Pl/a
area of the conductor increases resistance
value dicreases .so high leakage current flows it thats why
the area of the earthing pin is big compare yhe phase and
neutral pins.

Answer / guest

Simply to reduce resistance and allow fault current to flow
to earth.
