Metal-Clad Cable (MC) installation is addressed by which NEC article?

• A. Article 320
• B. Article 330
• C. Article 410
• D. Article 680

Answer: (B)

Metal-Clad Cable is covered by the NEC article dedicated to MC cable. That article lays out how MC cable must be installed, including listing and labeling, proper support and securing, protection from physical damage, fill and enclosure rules, and how terminations are made. It also explains how the metal armor interacts with grounding when the listing allows it. This distinguishes MC cable rules from other wiring methods that have their own articles, such as armored cables or other non-MC cables, which is why the MC-specific article is the correct reference.
