Difference Between Neutral Vs Earth wire

   

Neutral:         

•  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.  
• Neutral is a conductor that carries current in normal operation.  
• Neutral represents a reference point within an electrical distribution system.  

Earth "Ground"

•  Earth or Ground wire is a safety protective wire for the human body and electrical equipments from fault conditions. 
•  Earth is a conductor that carries no current in normal operation.
• Earth is a conductor that carries current under fault conditions such as insulation breakdown that occurs within electrical equipment.
