What color wire is typically used for grounding?

Grounding wires are critical in electrical systems as they provide a pathway for electrical current to safely dissipate into the earth in the event of a fault. The color code for grounding conductors is specified in the National Electrical Code (NEC), which is designed to ensure safety and consistency across electrical installations.

Green insulation or bare copper is used exclusively for grounding wires. This distinction helps electricians and anyone working with electrical systems easily identify grounding conductors, reducing the risk of accidental misconnection or short circuits, which can be dangerous.

In contrast, other colors like black and red are typically used for hot wires carrying current, while white is designated for neutral conductors. Using the correct color-coding is crucial in maintaining safety standards and minimizing the risk of electrical hazards in both residential and commercial installations.
