Which statement is NOT a requirement for an equipment bonding jumper?

• A. All portions of the grounding path shall be effectively bonded
• B. All portions shall be electrically continuous
• C. Only copper-clad conductors shall be used
• D. Electrical surfaces shall be free of nonconductive coatings

Answer: (C)

The statement regarding the requirement that only copper-clad conductors shall be used is not a requirement for an equipment bonding jumper. In the context of electrical installations, the primary consideration for bonding jumpers is not specifically about the material being copper-clad, but rather about their ability to provide an effective electrical connection. Equipment bonding jumpers can be made from various materials, provided they meet the necessary conductivity and resistance standards to ensure safety and functionality in an electrical system. The other statements emphasize crucial requirements for equipment bonding jumpers. An effective bonding path is essential to ensure that all components have an equal electrical potential, thereby reducing the risk of electric shock or fire hazards. It’s critical that all parts be electrically continuous to maintain conductivity throughout the grounding path. Additionally, ensuring that electrical surfaces are free of nonconductive coatings is necessary for the jumper to make effective contact, as these coatings can inhibit conductivity and compromise the safety of the bonding system.
