Earthing means connecting star terminal or neutral terminal of 3 phase sytem to earth directly or through resistance in case of generator & reactance in case of motor. These are used fo transformer, generator, motor, etc.

Grounding means connecting ground terminal of 3 phase sytem to earth or connecting body of equipment to earth. These are used for 3 phase system, transmission line & for protection from lightening etc.

This is really most confusing question asked by someone?...... Actually there is no any differences between earthing and grounding... you may say this is language difference as AMERICAN uses=GROUNDING, and BRITISH uses= EARTHING,

But as this question(inspired from differences bet neutral and grounding ) becomes very famous to confuse students, few writers starts differentiating it as........EARTHING: which is connected to dead part all times.

GROUNDING: intentionally connects when needs something to discharge like after C.B opens, we need to ground transmission line for a while so that all charging current gets discharge.

BUT,Again I insist there is no difference at all except language......

As You can see in any book, they write Grounding/Earthing(Grounding or Earthing), they never write Grounding and Earthing

Like bttu said, there is no difference between them and you can also add bonding to the group. earthing is basically used in britain and few commonwealth countries while grounding is used in america.

actually there are no such difference between earthing and grounding. Earthing word we use with our installation equipments in domestic as well as in substation,grid etc. And if due to some fault occur or by lightening some surge current passes to ground through earthing we called it some grounding occur..
