What color indicates a grounding conductor in electrical systems?

• A. Green or bare copper.
• B. White.
• C. Blue.
• D. Red.

Answer: (A)

Color coding for grounding conductors is about clearly identifying the protective earth path in electrical systems. The grounding conductor provides a low-impedance route to earth so fault current can trip protective devices and keep metal parts at safe potential. Because of this safety role, the standard is green or green with yellow stripes, and bare copper, for the equipment grounding conductor. This makes it easy to recognize and connect to the grounding system, outlets, and metal enclosures. White is typically neutral, not a ground; blue and red are usually used for hot or traveler conductors. So green or bare copper is the color that indicates a grounding conductor.
