I think not sure, we are using grounding if need to protect electrical circuits by connecting all passive and active elements to commen point inside devices, but earthing is used normally wherever electro-static currents resulted due to for example lightening such as GSM,MW towers and connected directly to the earth.

Earthing is the main source to protect the system which consists of various devices by connecting to the ground, whereas grounding is the process of connecting all the devices to a common point which is the earthing point.

Actually current is nothing its simply flow of charges.earthing is a wire which is common to all the points in a circuit used to complete the circuit, it is compulsory .while grounding is used to pass leakage of charges to the ground ,it is used for safety measure but not compulsory.

Grounding and Earthing are the same.  Grounding is US terminology while Earthing is British terminology.

Earthing is connecting the neutral point in 3 phase circuits to ground.
Grounding is connecting an electrical equipment  individually to ground.

Earthing is done by grounding a neutral of three phase system.
Grounding is used for protection purpose for current carrying devices.

grounding means connecting the live part (it means the part which carries current under normal condition)to the earth for example neutral of power transformer & earthing means connecting the dead part (it means the part which does not carries current under normal condition) to the earth for example electrical iron etc.

Every one must have heard of PG & PE in the same system. PG stands for Potential Ground, while PE for protective earth. Potential ground means the net effect of the potential at the point is zero (usually Neutral or return point) usually for protection of equipments. While PE is for protection of operator (or Human). Usually PE & PG are connected atleast at one point to avoid any floating potential.

The term "Earthing means that the circuit is physically connected to the ground, but incase of "Grounding" the circuit is not physically connected to ground, but its potential is zero, with respect to other point,which is also known as "Virtual Grounding."

Earthing is equipments, cables which is connected to system earth for permanent purpose, for example - panel body earthing, cable sheath earthing at termination, Transformer body earthing, neutral earthing, etc...-- Means connecting component to the ground potential which is mean to be remain at ground potential at normal working condition.

Grounding means - connecting part of equipement to ground/ earth for ensuring it is at zero potential and safe to work on. Means, components which suppose to have voltage for its normal working condition, but for maintenance work on it , it is connected to earth is callled "grounding"

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......

When we take out the neutral for a three phase unbalanced connection and send it to ground, it is called grounding. Grounding is done to to balance unbalanced load.

While earthing is used between the equipment and earth pit so as to avoid electrical shock and equipment damage.

Earthing is to protect the circuit elements whenever high voltage is passed by thunders or by any other source.

Grounding is the common point in the circuit to maintain the voltage levels.

Earthing actually means to,if there is an excessive voltage(not current) flowing in a power system,for the protection purpose it is connected to the earth with a help of rod,or by some other metals,so that the voltages flows to ground....

Neutral point or Grounding means,excessive or fault current flowing in the power system is also connected to the earth through rods,but which then act as a return path and gives back the current to the system itself..(i.e) the system cannot perform when it is in open loop,this neutral forms a closed loop...

Simply grounding is final outlet of whole appliance,building and any other. It have low resistance path. And neutral act as an circuit completor. Due to neutral whole power system works.but when we employ ground wire replace of neutral wire then obivously it consumes large power

Earthing and Grounding are two different simple concepts.

1.Earthing means connecting the dead part (it means the part which does not carries current under normal condition) to the earth. For example electrical equipment’s frames, enclosures, supports etc.

2.Grounding means connecting the live part (it means the part which carries current under normal condition) to the earth. For example neutral of power transformer.

Earthing and Grounding are nearly same where we connect the live parts of the machine to the zero potential(generally taken as ground or earth) in order to provide a bypass or excess or stray currents.But to be specific Earthing is done to the machine for the safety of people operating the machine whereas as grounding is done for the safety of machine itself.
If a machine is not properly earthed the stray currents may be passing through the body or casing of the machine which may get bypassed through the operating person if touched, so machine casing or body is earthed.
If a machine is not grounded properly the machine may suffer many problems during fault conditions like arcing grounds,over voltages etc., which may damage the machine so we generally ground the neutral of the machine( mainly in case of alternators) for safety of the machine.
