What is the maximum distance from strike termination devices to the ridge ends on pitched roofs?

The maximum distance from strike termination devices, such as lightning rods, to the ridge ends on pitched roofs is crucial for ensuring proper lightning protection. A distance of 2 feet is established as the maximum limit because it allows for optimal coverage for the protection system. Lightning rods are designed to intercept lightning strikes effectively, guiding the electrical charge safely into the ground without risking damage to the structure or its occupants.

If the distance exceeds the 2-foot limit, the effectiveness of the strike termination device may be compromised, increasing the risk that lightning may not be sufficiently captured and routed to ground. Therefore, adhering to this standard is vital in minimizing potential hazards associated with lightning strikes on structures with pitched roofs.
