Which color is associated with the grounding conductor in AC systems?

In AC systems, the color associated with the grounding conductor is green or green with a yellow stripe. This color coding is standardized to ensure safety and consistency across different installations and equipment. The green color (or the combination of green with a yellow stripe) clearly identifies the grounding conductor, which plays a crucial role in protecting both equipment and personnel from electrical faults by providing a low-resistance path for fault currents. By using this distinct color, technicians and electricians can quickly and accurately identify grounding conductors, minimizing the risk of accidents during maintenance or repairs.

The other colors listed, such as red, blue, and black, are typically used for other purposes, including phase conductors and neutral conductors, and therefore should not be confused with grounding conductors.
