MC cable stands for what?

• A. Metal-clad cable
• B. Armor-coated cable
• C. Metal sheathed cable
• D. Nonmetallic-sheathed cable

Answer: (A)

MC stands for metal-clad cable. This type has insulated conductors wrapped in a metallic sheath, usually steel or aluminum, which provides strong mechanical protection and can serve as a grounding path when properly terminated. The metal outer layer makes it more durable than nonmetallic-sheathed cable, making it suitable for installations where the cable may be exposed to physical damage or where a flexible alternative to conduit is needed. Some older terms refer to similar concepts as armor-coated or metal-sheathed cable, but the standard designation emphasizes the metal-clad outer sheath. Nonmetallic-sheathed cable, by contrast, uses a plastic jacket and lacks the metal armor.
