What is a neutral wire?

A neutral is the wire that carries back current from source to ground. This is our usual assumption and it is logically correct.

The neutral is a point of reference in an electrical distribution system that carries no current during normal operation, but which can carry fault current during faults.

You need to know the difference between neutral and ground. While neutral can be called ground, neutral cannot be considered neutral.

Today’s increased use of non-linear loads such as TV and Refrigerator has led to an increase in the demand for neutral wire.

Ground is useful to take the fault current from ground when insulation has been damaged.

These two statements can be summed up as: The purpose of neutral is to return the operator, while ground wire serves safety.

All electrical service panels have ground and neutral wires connected. If they are not connected, there is a risk to operator safety.
