Armored Cable (AC) is characterized by what feature?

Armored Cable (AC) is characterized as a flexible metal sheath enclosing insulated conductors. This design provides robust protection for the insulated wires contained within, making it suitable for various applications, especially in environments where mechanical damage is a concern. The metal sheath serves as a barrier against physical damage, while also offering additional grounding and lightning protection.

This feature allows AC cables to withstand more challenging conditions compared to non-armored cables. The flexibility of the metal sheath also enables easier installation in tight spaces or around obstacles. The combination of insulation around the conductors and the outer metallic sheath ensures both safety and durability, making it a popular choice in residential, commercial, and industrial settings.
