Neutral describes a conductor at or near earth potential that completes the alternating current supply, or more generally a state of having no net electric charge.
In electrical systems, the neutral is the conductor that completes the alternating current circuit and is connected to earth at the supply source. It provides a return path for current and is normally maintained at or near earth potential, distinguishing it from the energized line conductors. More broadly, neutral can also describe any condition of having no net positive or negative electric charge.
The neutral conductor plays an essential role in how power is distributed and balanced, carrying return current and serving as a reference for the system. Proper handling of the neutral is important to safe, correct operation, since it is tied to the grounding of the supply.
In commercial and industrial power systems, the neutral is part of the distribution that feeds equipment, and the conductors carrying it must be appropriately rated and identified. Correct identification and treatment of the neutral are fundamental to safe wiring practices.
Because the neutral is tied to the grounding of the supply and carries return current, its correct identification and treatment are fundamental to safe wiring, and the conductors carrying it are rated and marked so the system operates as intended.
At Windy City Wire, the focus on properly rated and identified low-voltage and power cable complements the distribution systems that include neutral conductors. Supplying dependable cable supports the safe, reliable handling of the conductors that complete a facility's electrical circuits.
