Is it advisable for a worker to install the air terminals and bases on the roof before laying out the conductor runs?

In lightning protection systems, it's essential to lay out the conductor runs before installing the air terminals and bases. This approach ensures that the configuration of the lightning protection system is optimally planned and executed. By laying out the conductor runs first, you can accurately assess the most effective positioning for the air terminals, allowing for a properly integrated system that meets safety and performance standards.

This method also helps in identifying any potential conflicts or obstacles that might arise once the air terminals and bases are in place. Proper planning avoids unnecessary rework and helps maintain the integrity of the roof while ensuring that all components work together cohesively. Additionally, deploying the conductor runs after the air terminals could lead to improper placement or insufficient coverage, which would compromise the system's effectiveness in protecting the structure from lightning strikes.
