Differentiate between grounding conductor and bonding conductor with examples.

Differentiate between grounding conductor and bonding conductor with examples.

• A. Grounding conductor ties equipment to earth; bonding conductor connects metal parts to each other to maintain equal potential; examples: ground wire, bonding strap.
• B. Grounding conductor connects metal parts to each other; bonding conductor ties equipment to earth; examples: bonding strap, ground wire.
• C. Both are identical, only used in different buildings.
• D. Grounding conductor is used for safety grounding; bonding conductor is for aesthetics.

Answer: (A)

The main idea is to understand two separate roles in electrical safety: grounding (earthing) and bonding. A grounding conductor is meant to connect electrical equipment to the earth. This provides a low-resistance path for fault current so overcurrent devices trip and the system has a stable reference to earth, helping to dissipate surges. An example is a ground wire running from the service panel to a grounding electrode, like a ground rod. A bonding conductor, on the other hand, is used to tie exposed metal parts together so they share the same electrical potential. This prevents dangerous voltage differences between metal surfaces that a person could touch, even if a fault occurs. An example is a bonding strap or jumper that ties metal water pipes or gas pipes to the electrical system, ensuring those parts stay at the same potential as other bonded metal components. These two paths usually connect to the same grounding electrode system at the service, but they serve different purposes: grounding establishes a earth reference and fault-current path, while bonding ensures equipotential among conductive parts to reduce shock risk.
