Armored Cable installation is governed by which NEC article?

• A. Article 320
• B. Article 400
• C. Article 330
• D. Article 314

Answer: (A)

Armored Cable has its own NEC article that specifically governs how this type of wiring must be installed. That article lays out how Armored Cable is constructed, where it can be used, and the requirements for protecting it from physical damage, securing and supporting it, and making terminations and splices. It’s intentionally distinct from other articles that cover different wiring methods, such as metal-clad cable or flexible cords, so the installation rules you apply depend on the exact type you’re working with. Understanding that dedicated article helps explain why it’s the correct reference for installing Armored Cable.
