Why should grounding systems be bonded with lightning protection systems?

Bonding grounding systems with lightning protection systems is essential to ensure that all systems are at the same potential during a lightning strike. This is critical because a lightning strike generates extremely high voltages and currents that can create significant potential differences between various grounded components. If the grounding systems are not bonded, these potential differences can lead to dangerous electrical surges that may cause damage to equipment, create hazards for individuals, and increase the risk of fires.

By bonding the grounding systems with lightning protection systems, it allows for a common reference point for electrical potential, which helps to minimize the risk of electrical shock and ensures the safe dissipation of lightning currents. This preventive measure is vital for both the safety of people and the protection of property during a lightning event.
