Which color designates ground conductors?

• A. Green
• B. White
• C. Black
• D. Red

Answer: (A)

Ground conductors are the safety path that carries fault current away to the earth, helping prevent shock or fire. To make wiring identification quick and reliable, electrical codes specify color coding. Green is designated for equipment grounding conductors, often shown as green or green with a yellow stripe (or even bare copper in some setups). This distinguishes it from other conductors: neutral wires are white (or gray) and hot or live conductors carry power and are colored black, red, or other colors. So green uniquely marks the grounding path, which is why it is the correct designation here.
