The difference between lightning conductor and the process of earthing ?

In the process of  earthing  there will be large amount of the current flowing through the line from the body of the equipment is properly because of very low resistance of the earth and the fuse in series with the equipment will blow and the equipment will be isolated from the line while
A lightning conductor is a metal rod made of thick copper and is buried deeply in the earth as this provides a low resistance path for any flow of electric charge between the earth and the atmosphere. This helps the building from a damaging discharge of electricity between the atmosphere and the building i.e a lightning strike.
