The safety ground conductor is usually colored:

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

Answer: (A)

Grounding conductors are identified by green to signal a protective earth path. This color helps electricians quickly recognize the safety ground, ensuring fault currents have a direct route to earth and allowing overcurrent protection to operate. In many codes, green insulation is standard, sometimes green with a yellow stripe, and bare copper is also used as a grounding conductor. The other colors listed are typically used for hot or traveler conductors in circuits, not for grounding, so they wouldn’t indicate the safety ground.
