Which NEC article outlines the requirements for armored cable?

  1. NEC 300

  2. NEC 320

  3. NEC 340

  4. NEC 360

The correct answer is: NEC 320

The National Electrical Code (NEC) article that specifically outlines the requirements for armored cable is NEC 320. This section provides guidelines regarding the construction, installation, and usage of Type AC (armored cable) wiring. It details what materials may be used, permissible locations for installation, and specific conditions under which armored cable can be employed effectively and safely. NEC 320 ensures that armored cable installations comply with safety standards, helping to protect electrical conductors from physical damage and potential hazards. Understanding this article is crucial for electricians to ensure their work adheres to the regulations and promotes safety in electrical installations. Other articles, such as 300, primarily cover general requirements for wiring methods, while 340 and 360 pertain to other types of cabling and installations that do not include armored cable specifically.
