Neutral Conductor
The grounded conductor in an electrical system that carries the unbalanced current back to the source and is connected to the neutral bus in the panel.
Detailed Explanation
In a 120/240V single-phase residential service, the neutral carries the difference in current between the two hot legs. The neutral is identified by white or gray insulation. The neutral must never be switched or fused (except at the service), and it must be properly sized to handle the maximum unbalanced load. In the main panel, the neutral bus is bonded to the grounding bus; in subpanels, they must be separate.
