What jacket/marking options are acceptable for interior bonding/grounding conductors?

• A. Green jacket
• B. Green with yellow stripe
• C. Properly marked with green tape or labeling
• D. All of the above

Answer: (D)

The key idea is how interior bonding/grounding conductors are identified. A bonding/grounding conductor can be clearly recognized by any of several acceptable methods: using a green jacket on the conductor, using green with a yellow stripe, or properly marking the conductor with green tape or labeling. Each option communicates that this is the bonding/grounding path, meeting the color-coding and identification requirements. Because all three methods achieve the same clear identification, any of them is valid, which is why “All of the above” is the best choice.
