In residential wiring, which color is typically used for the neutral wire?

In residential wiring, the neutral wire is typically represented by gray or white. This is an important safety feature that helps distinguish different types of wires within an electrical system. The neutral wire serves the crucial role of carrying current away from the electrical device and back to the service panel, enabling the completion of the electrical circuit.

The standardization of wire colors in electrical systems is guided by the National Electrical Code (NEC), which is designed to promote safety and consistency. By identifying the neutral wire with gray or white, it reduces the risk of confusion during installation and maintenance, helping ensure that individuals working with electrical wiring can do so safely.

Understanding these color codes is vital for anyone involved in fire investigation, as miswiring or incorrect identification of these wires could potentially lead to electrical faults or hazards that may contribute to fire incidents.
