What type of clamp is required for bonding in plumbing?

1. Plastic clamps

2. Wooden clamps

3. Copper clamps

4. Dielectric clamps

The correct answer is: Copper clamps

The correct choice is the use of copper clamps for bonding in plumbing due to their excellent electrical conductivity and corrosion resistance. When bonding metal piping systems, particularly those involved in electrical grounding, copper is preferred because it effectively creates a reliable electrical connection. This is crucial to prevent stray voltage from affecting water systems and to ensure that electrical faults are properly directed to ground without causing hazards. Copper clamps facilitate proper bonding between different metal pipes, ensuring compliance with safety codes and standards. This helps to mitigate the risk of electrical shock and promotes overall safety in plumbing systems. The other materials listed do not offer the same level of conductivity and durability under varied environmental conditions, which is why copper is the industry standard for bonding in plumbing applications.
