Which statement best differentiates grounding from bonding?

• A. Grounding creates a reference point; bonding ensures metal parts are at same potential to prevent shock.
• B. Bonding creates a reference point; grounding ensures metal parts are at same potential to prevent shock.
• C. Grounding prevents shock by insulating.
• D. Bonding is the same as grounding.

Answer: (B)

Grounding and bonding serve different roles in a electrical system. Bonding links all exposed metal parts that could become energized so they sit at the same electrical potential, giving you a common reference point across the equipment. This equal potential reduces the chance of a shock if a fault makes contact between parts. Grounding, on the other hand, ties the system to earth to provide a stable earth reference and a low-impedance path for fault current to return to the source so protective devices can trip quickly. The statement aligns with this distinction by saying bonding creates a reference point, while grounding helps keep metal components at the same potential to prevent shock. Other options mix up the purposes—grounding is not simply about insulation, and bonding is not exactly the same as grounding.
