Which process electrically connects metal parts of an electrical system to ensure they are at the same electrical potential?

• A. Voltage
• B. Grounding
• C. Bonding
• D. Current

Answer: (C)

Bonding is the process of electrically connecting metal parts of an electrical system so they share the same electrical potential. By tying together enclosures, frames, rails, and other conductive components with bonding conductors, you prevent voltage differences between those parts, which reduces shock risk and helps avoid arcing during faults. Grounding, while related, connects equipment to earth to establish a reference and provide a fault current path; it doesn’t by itself ensure equal potential among all metal parts. Current and voltage are quantities describing electrical behavior, not methods of making parts equipotential.
