Which color is generally accepted for a grounded conductor?

The color that is generally accepted for a grounded conductor is white. This convention is established in the National Electrical Code (NEC) and is widely recognized in electrical wiring practices. The white color indicates a neutral conductor, which is one that is connected to the ground at the main electrical panel for safety purposes. This helps prevent electric shock and ensures that the electrical system operates correctly.

In residential wiring, the grounded (neutral) conductor is typically distinct from other conductors that serve different functions, such as phase or hot conductors, which are often black or red. Green is reserved for equipment grounding conductors, which serve a different purpose than grounded conductors. Following these color codes helps maintain safety and consistency in electrical installations, making it easier for electricians to understand and work with wiring systems.
