Should main conductors maintain a horizontal or downward course free of "U" or "V" pockets?

Main conductors should maintain a horizontal or downward course free of "U" or "V" pockets to ensure that lightning protection systems are effective and reliable. This design prevents water accumulation, which can lead to corrosion and failure of the conductors over time. Additionally, maintaining a clear and direct path for conductors enhances their ability to carry lightning current safely to ground without the interference that can be caused by bends or pockets.

When conductors are free of dips or bends, they reduce the risk of creating weak points in the system that could compromise its performance. This practice is critical in maximizing the reliability of the lightning protection installation. Ensuring a direct run minimizes resistance and optimizes the discharge of electrical energy, which is crucial for protecting structures from lightning strikes.

Other options suggest alternatives that could inadvertently lead to complications or weaken the integrity of the lightning protection system. Therefore, maintaining a consistent horizontal or downward course without pockets is essential in upholding the performance standards of lightning protection systems.
