What best describes the difference between grounding and bonding?

• A. Grounding establishes a reference to earth; bonding ties conductive parts to prevent potential difference.
• B. Grounding and bonding are the same.
• C. Bonding creates a protective coating.
• D. Grounding increases voltage.

Answer: (D)

Grounding and bonding serve different safety roles. Grounding provides a reference to earth and a path for fault current to return to the ground, helping stabilize system voltages and enabling protective devices to trip when a fault occurs. Bonding connects all exposed conductive parts so they are at the same electrical potential, preventing a dangerous voltage difference between those parts. The best description is that grounding establishes a reference to earth; bonding ties conductive parts to prevent potential difference. This distinction matters: grounding deals with the overall system’s relation to earth and fault current paths, while bonding ensures that metal parts don’t end up at different voltages relative to each other, which could cause shock. Grounding does not increase voltage; it helps keep voltages aligned with earth potential and provides a reliable path for fault current to trip breakers. The statement that grounding increases voltage isn’t accurate. Bonding isn’t about creating a protective coating, and grounding and bonding are not the same process.
