(OP)
Could anyone tell me how to differentiate Grounding and Earthing? It seems to be no harm to swap but I still want to know if there is any difference.
Thanks!

RE: grounding v.s. earthing
Can't remember clearly which one was which, but if forced to answer, I would say that grounding was the former, and earthing was the latter.
I suppose if both terms are used in the same specification, then there is a difference, but if the terms are used singly, then they might refer to either part of the system, or both.

The meaning for all is to electrically connect equipment to earth ground electrical potential.

perhaps 'earthing' is a more global term, then. (

RE: grounding v.s. earthing
In Naval engineering, I've never heard the term "earthing", maybe because we don't ever copnnect things to "earth"; whereas on land-based applications I can envisoin the term as commonly used.

People in the UK usually understand both, in the US I've found people who didn't have a clue what I meant by earthing.

RE: grounding v.s. earthing
Do you think, perhaps, that the terms may differ when the equipment that they are applied to is considered?
Both terms relate to a voltage potential.
If you have a piece of electronic equipment that needs to be shielded from some sort of interference, or that needs to be shielded to prevent it from interfering with something else, you may well connect it, literally, to earth.
That is, the best electrical connection you can make to earth (dirt, backyard, seawater) voltage potential. to achieve a zero volt level.
If you have a piece of equipment, machinery, vehicle say, then the term 'ground' could be used to describe that equipments zero voltage or 'common' connection, which may not ge at earth potential.

Earth and earthing is very much an electrical term and is dominant in the UK. 'Ground' on an electrical draswing usually means that the drawing originated outside of the UK. I do use 'ground' quite often on Eng-Tips, mainly so you furriners from the US can understand what I am talking about.

When you search for 'Earthing' you get redirected to the 'Ground (Electricity)' page.....They are one and the same.

Earthing is some thing that goes into the earth as the roots of Brussels sprouts
Earthing is also an electrical device to discharge the electricity into the earth

Not true. Europeans have set foot on space craft/stations off our planet. Just not on another heavenly body as such.

RE: grounding v.s. earthing
back here after a couple of days, I find the threads are bit off the subject.
RE: grounding v.s. earthing
grounding= connection of elecrical equipment, housings, etc to a common zero which does not necessarily have the same potential as the earth at that point. E.g. connecting certain parts of an electrical hand drill via the ground wire (one of the three in the cable) to the ground of the electrical supply network of the building. This ground might not have the same potential as the earth in that vicinity. I imagine to remember that this is more for protection of the equipment and does not necessarily protect the person operating the drill. I also imagine to remember that this type of grounding was more important in the UK than in continental Europe due to some difference in the history of and in the philosophy in setting up the domestic and industrial electrical networks. I do not know the details of this difference.
Earthing = the physical connection of equipment (including non-electrical equipment) to the earth in the immediate vicinity of the equipment. This is to prevent static build-up in equipment and this protects the person operating or touching equipment. E.g. in refineries: connection of a vessel shell via a thick enough cable to a rod in a nearby water well which dissapates the electricity to earth. Such equipment will have near earth potential.
Bonding = the electric bonding of equipment to each other so that all such equipment does have a conducting path to the earth.
So, there appears to be a real difference in the two terms, or they can both be used interchangeably in the two meanings.

RE: grounding v.s. earthing
In answer to your question, the UK public utility low voltage distribution system and installations directly fed from it are based on the 'EEBADS' principle. EEBADS is an abbreviation of 'Earthed Equipotential Bonding and Automatic Disconnection of Supply'. The connection to earth is fundamental in allowing most protection schemes deployed on the LV network to detect and disconnect faulted circuits.
There are some unusual installations which do not have any earth-referenced electrodes or conductors present, creating an earth free environment. These are rare indeed in the UK. Slightly less rare but still unusual are installations where the supply is not earth-referenced at its origin. Normally the neutral point of the distribution transformer LV winding is connected directly to an earthing electrode. I believe ungrounded systems are more common in the US than over here.
This is far too technical for this forum - if you want further details drop a post in the Power Engineering forum.

BUT:
Earth or Ground, electricity doesn't just dissipate into the ground (or earth), it has to go somewhere (as in all circuits), it completes the circuit by returning to the substation via the substations' earth mat.
