Which color of wire is typically used for grounding in residential wiring?

The color used for grounding in residential wiring is typically green or bare. This color coding is standardized in the National Electrical Code (NEC), which mandates that grounding wires must be easily identifiable to ensure safety during installation and maintenance. The use of green or bare wire helps electricians quickly recognize grounding conductors, reducing the risk of accidental contact with live wires.

Grounding wires serve the critical function of providing a safe path for electrical current to dissipate in the event of a fault, which is essential for protecting both electrical systems and individuals. By adhering to these color conventions, electricians ensure compliance with safety standards and promote a better understanding of electrical systems.

Other colors like red, black, and white have specific roles in electrical systems; red is often used for secondary hot wires, black for primary hot wires, and white for neutral conductors. However, they do not serve the same purpose as grounding wires, highlighting the importance of using the correct color to indicate specific functions within electrical installations.
