Article 324 specifically addresses what type of cable?

Article 324 of the National Electrical Code (NEC) specifically covers Flat Conductor Cable, designated as Type FCC. This article provides the requirements and guidelines for the installation and use of flat conductor cable systems, which are utilized for various applications, including in residential and commercial buildings. Type FCC cables are characterized by their flat configuration, allowing for easier installation in constricted spaces and less bulk compared to traditional round cables.

The code outlines specific requirements related to the construction, performance, and installation practices for this type of cable to ensure safety and reliability in electrical systems. This includes aspects such as conductor materials, insulation types, and mechanical protection.

The other choices, while they reference valid cable types and NEC articles, do not pertain to Article 324. Armored Cable (Type AC) is covered under Article 320, Integrated Gas Spacer Cable has its own regulations, and general conductors for wiring are discussed under different sections applicable to a broader range of wiring practices. Therefore, understanding Article 324 focuses specifically on the flat conductor cable and its regulations, making it the appropriate answer.
