What is the requirement for bonding metal bodies that are inherently bonded through construction?

The requirement for bonding metal bodies that are inherently bonded through construction is that they require no additional bonding. This is based on the principle that if the metal components are already effectively electrically bonded together through their construction (for example, via welds, bolts, or other joins), they do not need further bonding to meet safety or protective standards. This is important because inappropriate additional bonding could potentially introduce more risk or complications in the system, rather than providing added safety.

Inherent bonding already provides a continuous electrical path that is necessary for the proper functioning of lightning protection systems and ensures that any lightning strike is safely channeled away. Regular checks, insulation, or painting—options associated with maintenance or enhancement—are not mandatory in this context since the existing construction adequately fulfills the bonding requirements.
