What type of bonding jumper is used for lightning protection at the BCES parking lot pole bases?

The use of a bonding jumper for lightning protection is essential to ensure that any electrical energy from a lightning strike is effectively directed to the ground, minimizing the risk of damage to structures and equipment. In the context of the scenario presented, the correct answer identifies the appropriate size and type of conductor to be used for this purpose.

Copper-clad stranded wire is particularly advantageous for bonding jumpers due to its flexibility and conductivity. The 6 AWG copper-clad stranded option strikes a balance between having adequate current-carrying capacity while remaining manageable and easier to work with than larger gauges. This gauge is generally accepted for grounding and bonding in applications requiring lightning protection, as it can adequately handle high surge currents expected during a lightning event.

The other options, while discussing different gauges and constructions of conductors, may either not meet the required standards for safety and effectiveness in lightning protection or may not be optimal considering the balance between performance and ease of installation. Therefore, selecting the 6 AWG copper-clad stranded bonding jumper stands out as the most suitable choice for ensuring safety and compliance in the described environment.
