Answer Posted / prashant
when ever we talk about fault current. it always means a heavy current. fault current always needs a path to be grounded. since it is large so it obviously needs conductor having low resistance. since if resistance is high then on passing current through it will produce heat by formula (I^2R). again by seeing formula of resistance
R=P*l/a
increasing the area will reduce the resistance and hence reducing heat energy.
that is why earth wire is kept thick...
