Difference Between Earth and Neutral

Neutral:

  • Neutral is the return path for an AC circuit that carries current in normal condition.
  • This current could be primarily because of the phase current imbalance. The magnitude of this current is a fraction of phase current or in a few cases even double of the phase currents.

Earth:

  • Earth, also known as a ground, is used for safety concerns against leakage or residual currents in the system.
  • While phase and neutral are connected to main power wiring, the earth is connected to the body of equipment which doesn’t carry current in normal conditions but in case of any insulation failure, is supposed to carry some minor current.

Earth Neutral
It is the least resistance path and is used as a safety purpose against residual currents In an AC circuit which carries current in normal condition, it is the return path, it balances the load
In normal condition, it doesn’t carry any current but in case of insulation failure, it might carry minor current A neutral wire is always charged
It cannot be turned into neutral It can be turned into earth
It can come from a neutral line or can be separately executed It comes from a neutral line
Earth is the surging point of appliances Neutral is the return path of the electrical current supply, it is also called a reference point
