When lightning conductors are to be concealed, where can they be installed?

The correct answer indicates that lightning conductors can be installed in multiple concealed locations, including behind the exterior wall facing, between wall studs, and under roofing materials. This versatility is essential for ensuring effective lightning protection without compromising the aesthetic appearance of a building.

Concealing the lightning conductors helps reduce their visibility while still maintaining their functionality. Installing them behind exterior walls allows for the protection system to be integrated seamlessly into the building's structure. Similarly, placing conductors between wall studs provides a discreet protection method while still allowing for effective grounding and electrical conduction. Lastly, installing conductors under roofing materials ensures that they can safeguard the uppermost part of the structure from lightning strikes without being exposed to the elements which could lead to deterioration.

Overall, using multiple locations like these allows for a comprehensive approach to lightning protection that accommodates design standards and safety requirements. These practices collectively contribute to a more effective lightning protection system while ensuring aesthetics are preserved.
