What does the color white/light gray signify in wiring?

In wiring, the color white or light gray is designated to signify a grounded conductor, also known as a neutral conductor. The neutral wire serves a critical role in an electrical system by providing a return path for electric current back to the source. This is essential for completing the electrical circuit. The neutral wire is typically connected to the ground at the main electrical panel, which helps to stabilize the voltage levels and provide safety by mitigating the risk of electric shock.

Moreover, the use of white or light gray for neutral conductors is standardized in the National Electrical Code (NEC), which helps ensure consistency and safety in electrical installations. Recognizing the correct color coding is crucial for anyone working with electrical systems, as it aids in proper installation and maintenance, enhancing safety and functionality.
