Which color is typically associated with the neutral wire in a standard electrical circuit?

In standard electrical wiring practices, the neutral wire is typically associated with the color white. This color coding is essential for identifying the function of each wire within a circuit, ensuring safety and proper connections. The neutral wire serves as the return path for current back to the electrical panel and helps complete the circuit.

Using white for the neutral wire is a convention established by the National Electrical Code (NEC) in the United States. This consistency allows anyone working with electricity—whether in new installations or repairs—to easily recognize the neutral wire, thus reducing the risk of accidental contacts or miswiring.

In contrast, red and black wires are typically used for hot wires, with black being the most common for the primary hot wire and red often used as a secondary hot wire in circuits where two hot feeds are present. Green wires are generally used for grounding purposes. This clear color coding is crucial in maintaining the safety and functionality of electrical systems in residential settings.
