What must be verified for ground clamps that are used for bonding?

Ground clamps used for bonding play a crucial role in creating a low-resistance path for electrical grounding. Verifying the usage listing of ground clamps ensures that they are suitable and compliant with the specific requirements of the National Electrical Code (NEC) and relevant standards. A usage listing indicates that the clamp has been tested and approved for specific applications, such as bonding in electrical systems, which is vital for safety and system integrity.

Understanding the usage listing helps ensure that the clamp can effectively handle the electrical loads and environmental conditions it will face in its application. This verification is critical for maintaining a safe electrical installation and preventing potential failures that could lead to hazards.

While other aspects such as material type or manufacturer's warranty may be relevant in certain contexts, the usage listing is directly tied to both compliance with regulations and practical functionality in bonding applications.
