Answer :

Sr. No.
Equipment earthing
Neutral earthing
1 Connection of the non-current carrying metallic parts of the electrical equipment to earth is called as equipment earthing.
Connection of the neutral point of three phase transformer, generators, motors etc. to earth is neutral earthing.
2 It is provided for protection of human being from electric shocks.

4 Equipment earthing is provided through Pipe earthing, Plate earthing.
Neutral earthing is provided through solid earthing, resistance earthing and reactance earthing.
5 It does not provide any means for protection system against earth fault.
It provides suitable means for earth fault protection system.
6 It is an equipment earthing.
