What is the primary function of secondary conductors in lightning protection systems?

The primary function of secondary conductors in lightning protection systems is to accomplish bonding and connections within the protection zone. Secondary conductors are crucial for ensuring that all conductive parts of a structure or system are at the same electrical potential during a lightning event. This minimizes the risk of side flashing, where lightning jumps from a high-potential conductor to a lower-potential one, potentially causing damage or injury.

By effectively bonding various components of the lightning protection system together, these conductors help direct the electrical charge safely to the ground, maintaining a uniform potential and safeguarding both the structure and its occupants. This bonding is essential for the overall effectiveness of the lightning protection system, ensuring that the entire system operates as a cohesive unit.

While other aspects such as conducting lightning away from structures and connecting ground rods play important roles in lightning protection, it is the bonding and connections facilitated by secondary conductors within the protection zone that are fundamental for safety and system integrity.
