Answer / karan rana

The neutral is the normal "return" wire: in systems where
the load is supplied from only one hot (or "live") wire, the
neutral completes the circuit and carries current back from
the load to the power station.

The ground or "earth" wire is a circuit's safety protective
wire that normally carries no current

Answer / avd

Neutral - Neutral is the star point of a 3 phase
transformer with star connection of secondary. This star
point will have zero potential under balanced load
condition. This star point may or may not be connected to
earth depending on requirements of power system.
Earthing - Earthing is ground potential (ZERO) connected to
mother earth via earthing pit.

Answer / amal kumar mahata

If we thinking the MCCB the live line and nutral line monitoring the system. If any abnormality found the system load it will functioning and cut off system. Where as earth wire have zero potential and it should be connected to earthpit.

Answer / g narayanarao

Neutral is star point of the transformer of secondary winding and it protect the system and named as system earthing.
Earthing is solid grounding which protect the human and animals and named as equipment earthing.
