Ground clamps used for bonding must be what type?

Ground clamps used for bonding must be listed for the specific purpose because this ensures that they meet the safety and performance standards established by relevant testing organizations. The listing indicates that the clamps have been rigorously tested for their ability to withstand environmental conditions, electrical loads, and other operational parameters that are critical for bonding applications. Using a listed ground clamp ensures compliance with the National Electrical Code (NEC) requirements, thereby enhancing the safety and reliability of the electrical system as a whole.

In contrast, while ground clamps may be made of copper, galvanized metal, or designed as universal types, these characteristics alone do not guarantee compliance with safety standards. The focus on having clamps that are specifically listed for bonding applications is crucial for ensuring that they perform as expected under various conditions and provide a reliable connection to ground, which is essential for the protection of people and property from electrical hazards.
