Bonding means the exact same thing as grounding in all contexts.

• A. True
• B. It depends on the context
• C. It is unrelated to safety
• D. False

Answer: (D)

Bonding and grounding are related but not identical in electrical safety. Bonding means connecting conductive objects so they share the same electrical potential, which helps prevent dangerous voltage differences between things you might touch at the same time. Grounding, or earthing, means connecting a part of the system to the earth to provide a low-impedance path for fault current and to stabilize voltages.

In practice, bonding is about equalizing potential between components—like linking metal tanks, pipes, or equipment so they don’t end up at different voltages if a fault occurs. Grounding provides a reference to earth and a route for fault current to trip protective devices, helping keep exposed parts at earth potential during faults. They can work together in a safety system, but they are not the same thing in every context.

So the statement is false; bonding and grounding are distinct concepts with different purposes, even though they’re both important for safety.
