MC cable is a type of what?

MC cable is a type of what?

• A. Thermoplastic-insulated wire
• B. Metal-clad cable
• C. Armored cable
• D. Fiber-optic cable

Answer: (B)

Metal-clad cable is a type of cable that has a metallic outer sheath around insulated conductors, giving mechanical protection and often a grounding path. This is what defines MC cable, distinguishing it from other options. The thermoplastic-insulated wire refers to individual conductors, not a full cable with a metal jacket. Armored cable describes a different construction with armor around conductors and usually a separate jacket. Fiber-optic cable carries light signals and contains no electrical conductors. So, the correct classification for MC cable is metal-clad cable.
