Which color is designated for a neutral wire in electrical systems?

In electrical systems, the neutral wire is designated by the color white. This standardization is crucial for safety and consistency in electrical wiring practices. The neutral wire plays a vital role in providing a return path for current back to the electrical panel, completing the circuit. By using white for the neutral wire, electricians and anyone working with electrical systems can easily identify it among other wires, thus minimizing the risk of mistakes when installing or repairing electrical circuits.

The use of other colors for wires, such as red, black, or yellow, typically indicates different functions. For example, black is commonly used for hot wires, which carry live current, while red may also indicate hot wires or secondary hot wires in certain configurations. Yellow is less commonly used but can also be associated with specific applications or circuits. Recognizing these color codes enhances safety and ensures that electrical installations adhere to established guidelines.
