The neutral conductor (also referred to as the grounded conductor) is used in order to establish a ground reference in an electrical system. Without this reference, circuit breakers would not reliably trip (most likely, they would not trip at all) in response to an overcurrent condition. This is a dangerous situation which would lead to destruction of equipment and loss of life.

The other primary reason to include a neutral conductor is to stabilize the voltage in a single phase or three phase distribution system. Without a neutral conductor the voltage on ungrounded (hot) conductors would raise or lower due to varying load conditions. This erratically fluctuating voltage would cause damage to equipment and potentially harm people as well.

The neutral conductor is very important to ensure safety in electrical circuits.
