Which option is NOT a stated use of armored cable in outside plant installations?

• A. Prevent Rodent Damage
• B. Protects from Dig-Ups
• C. Increase Pulling Tension
• D. Conduct Lightning

Answer: (D)

A key concept here is what armored cable is designed to do in outside plant installations. Its primary purpose is to provide physical protection for the conductors that run underground or in exposed routes. The armor helps guard against damage from animals and from being dug up, and it also supports the installation process by increasing the cable’s pulling strength, making installation safer and more reliable in rugged environments.

Lightning conduction, on the other hand, isn’t a stated purpose of armored cable. Lightning protection relies on proper grounding, surge protection, and appropriate shielding and bonding practices, not on the armor itself. While the metal sheath could be bonded to ground in some systems, that’s not considered a designed function of armored cable in outdoor installations.
