What color is the ground conductor?

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

Answer: (A)

Green is used for the ground conductor because it identifies the protective earth path. This color signals a safety route that carries fault current back to the source so the overcurrent device can trip and interrupt power. Green (often with a yellow stripe) is reserved for equipment grounding, keeping it distinct from neutral (white) and hot conductors (such as black, red, or blue). By using green for the ground, electricians can quickly recognize the return path to the earth and ensure proper bonding to the enclosure and grounding electrode system.
