What type of connector should be used for bonding conductors?

The use of listed connectors or clamps is the most appropriate choice for bonding conductors. Listed connectors are specifically designed and tested to meet specific safety and performance standards. They ensure reliable connectivity, which is crucial for maintaining a safe grounding and bonding system. This is particularly important in minimizing resistance and ensuring that fault currents can be safely conducted to the ground, thereby protecting both equipment and personnel from electrical hazards.

The requirement for connectors to be listed implies that they have undergone rigorous testing by a recognized testing laboratory, ensuring they can perform effectively under the expected conditions. This adherence to standards ultimately contributes to the safety and reliability of the electrical installation.

Other types of connectors, such as non-metallic or pressure-type connectors, may not provide the same level of assurance regarding performance or safety, hence they are not specified for bonding conductors. Using any connector available could compromise the integrity of the grounding and bonding system, leading to potential risks in an electrical installation.
