If a conductor is used solely for bonding, how should it be sized?

Sizing a conductor used solely for bonding should align with bonding conductor requirements established in relevant safety standards and codes. Bonding conductors are intended to provide a low-resistance path to ground that ensures electrical continuity and minimizes the risk of electrical shock or fire.

These requirements typically specify the minimum size of bonding conductors based on factors such as the types of systems being bonded, the materials used, and the potential fault currents. By following these guidelines, the bonding conductor can effectively perform its intended function of safely dissipating electrical energy into the ground or connecting various conductive parts to ensure they are at the same electrical potential.

Other considerations, such as the height of the structure or the material type, are generally more relevant to main lightning conductors or other types of conductors and do not apply to bonding conductors, which specifically require compliance with outlined bonding conductor specifications.
