What is the difference between neutraling & grounding?

Question

i just need the basic difference.

Answer 1

I don't think the term "neutraling" is really correct.

A ground is a safety connection that ensures that a metal case cannot become hot and shock anyone.

A neutral is a current carrying conductor that has been connected to ground. This ensures that a protection device (fuse or breaker) will operate if the "hot" wire has a fault (becomes grounded)

Answer 2

Neutraling: having no net electric charge.

Grounding: Connect to a ground, of electrical connections for safety reasons

You can find Live, Neutral & Ground wires in electric wiring.

Answer 3

In 3 phase wiring each of them differing in phase by 120degrees, there is a neutral wire also. Domestic supply (or any appliance or gadget) gets 1 phase wire & 1 neutral wire (for return path) for supply. The voltage is measured with reference to neutral wire (V(neutral)=0 V).

Most of appliances and gadgets have metal shells or chassis in some cases, which are not electrically connected to the internal circuit. This needs to be at ground potential to prevent 'shock' to the user. In household wiring a thick (copper) wire is run terminating in the ground (Earth), as Earth absorbs all voltages. Any voltage noticed on the shell or chassis is instantly shorted to ground potential which is zero. This is the utility of the third thicker pin. But it must be ensured periodically that the 'grounding' continuity exists. Any break or loose contact in ground wiring, loses effectiveness of grounding, rendering it null and leading to a 'shocking' situation.
