Which type of connector would be used for securing conductors to the structure?

The use of a fastener is essential for securing conductors to a structure, as it provides a reliable means of attachment that can withstand environmental factors like wind, rain, and temperature changes. Fasteners ensure that conductors remain in place and maintain proper alignment, which is crucial for effective lightning protection systems.

Ground terminals, while important for establishing an electrical connection to the ground, are not typically used for securing conductors to structures. Air terminals serve the purpose of intercepting lightning and directing energy safely to the grounding system, and conductors are the electrical pathways themselves. Therefore, while all these components play vital roles in a lightning protection system, fasteners specifically address the need to securely attach conductors to the physical structure, making them the correct choice in this context.
