Armored cable is designed to prevent damage from which of the following?

Armored cable is designed to prevent damage from which of the following?

• A. Rodent and crush protection
• B. Water intrusion
• C. Fire damage
• D. UV degradation

Answer: (A)

Armored cable uses a metal outer layer around the conductors to provide strong mechanical protection. That armor resists crushing and makes it much harder for rodents to bite through the insulation, which is exactly what you want in installations where physical damage or pest exposure is a concern. Water intrusion, fire damage, and UV degradation are addressed by other design features—waterproof jackets or conduit seals for moisture, fire-rated insulation for flame resistance, and UV-stable jacket materials for sunlight exposure. So the armor’s primary role is protecting the cable from physical damage and pests.
