How should a screw main bonding jumper or system bonding jumper be identified?

• A. With a red finish
• B. With a green finish
• C. With a blue finish
• D. No identification needed

Answer: (B)

A screw main bonding jumper or system bonding jumper is specifically identified with a green finish to signify its purpose related to grounding and bonding. This color coding is established to promote consistency and safety in electrical installations. The green finish is universally understood in the electrical field to indicate grounding conductors, which include bonding jumpers. Proper identification helps ensure that personnel can quickly recognize the role of the jumper, reducing the risk of mistakes during maintenance or modification of the electrical system. This color-coding standard supports safety protocols, aiming to prevent electric shock hazards associated with improper handling of grounding and bonding components.
