Which of the following is true regarding bonding of metallic bodies to the lightning protection system?

Bonding metallic bodies to the lightning protection system is crucial as it serves to equalize the electrical potential among various metallic components during a lightning strike. This potential equalization is essential in preventing arcing – which can occur when there is a significant difference in voltage between two points, leading to a sudden discharge. By ensuring that all metallic bodies are effectively bonded and connected to the lightning protection system, it minimizes the risk of uncontrolled electrical discharges that could cause damage or injury.

The need for bonding extends beyond just preventing arcs; it ensures the safety and integrity of both the structure and its occupants. This practice is vital irrespective of the size of the structure or the types of metallic components involved. Thus, bonding is an integral aspect of lightning protection systems, contributing significantly to overall safety during such natural events.
