What color wire is typically used for ground connections?

The typical color designation for ground connections in residential wiring is green or bare copper. This standard is important for safety, as it clearly identifies ground wires, which play a crucial role in providing a safe path for electricity to flow back to the ground in the event of an electrical fault. The use of a designated color, such as green, helps to prevent confusion with other wires that carry current, such as hot and neutral wires. Having ground wires distinctly colored or uninsulated (bare copper) ensures that electricians and homeowners can easily recognize and work with them, reducing the risk of electrical shock and other hazards.

This practice is in accordance with the National Electrical Code (NEC) and is widely followed to maintain safety and consistency across electrical installations.
