What color identifies a grounded conductor in electrical wiring?

In electrical wiring, a grounded conductor is typically identified by the colors white or gray. These colors are part of the National Electrical Code (NEC), which establishes standards for safe electrical installations. The white or gray wire serves as a neutral conductor that is connected to ground at the main electrical panel, providing a path for current to return to the ground in case of a fault.

The use of specific colors for wiring helps ensure safety and prevent confusion during electrical work. This coding system allows electricians and anyone working with electrical systems to easily identify conductors and understand their functions. For instance, using a black or red wire, which are designated for hot conductors, for grounding purposes would create significant risks of electrical shock or short circuits.

In summary, the identification of grounded conductors with white or gray ensures that electrical systems are implemented according to safety codes, minimizing the risk of hazards.
