Earth
- it is used for safety purpose. i.e whenever leakage
current pass through electric machine body,earth will
conduct directly to earth.So it is prevent electric shock
to human body.
- In 3 phase star connection its act as a neutral & same
point connected to ground.

Neutral
- It is one of the wire in AC circuit.
- It is used for return path of the circuit in single
phase & three phase.

- - earth can use as neutral but neutral can't use as earth.
