What type of cable is typically wrapped in metal for protection?

Armored cable is specifically designed to provide an additional layer of protection through its metal wrapping. This metal armor, which can be made from aluminum or steel, serves multiple functions: it shields the inner wires from physical damage, minimizes the risk of electromagnetic interference, and provides a level of moisture resistance. This is particularly important in environments where cables might be exposed to potential hazards or harsh conditions.

In contrast, electrical metallic tubing and conduit options are generally used for routing and protecting wiring but do not inherently include the conductors themselves. Nonmetallic sheathed cable, while widely used for residential wiring, lacks the added physical protection of a metal sheath, making it less suitable for environments where extra durability is required. Thus, armored cable is recognized for its robust construction and suitability in applications where enhanced protection of electrical wiring is paramount.
