Neautral Wire vs Earth Wire - Difference Between Neutral Wire and Earth Wire

The Neutral wire and Earth wire are normally connected together at your service panel board. Neutral wire is the normal or return path of the circuit. Earth wire is a safety protective wire for the human body and electrical equipment's from fault condition.

Neautral Wire vs. Earth Wire

⇒ Neutral wire is directly connected to the neutral point of the supply system.

⇒ Earth wire may be directly connected to the neutral point to the supply system. 

⇒ Neutral wire serves as a return conductor.

⇒ Earth wire may carry current only in case of a fault.

⇒ Neutral wire is potential at some point may be substantially far from zero. 

⇒ Earth wire is supposed to be at zero potential.

⇒ Neutral wire is therefore insulated from the pole on which it is supported. In this case, the insulator is smaller size than the one supporting the phase conductors.  

⇒ Earth wire is not mounted on any insulator and is it direct metallic contact with the support metals work.

⇒ Neutral wire may not be connected to earth at an intermediate point in the line.

⇒ Earth wire must be connected to earth at least 3 places in a kilometer or at 4 places an a mile.
