Which type of cable is mentioned in Article 334?

• A. Type MC
• B. Type NM, NMC, and NMS
• C. Type TC

Answer: (B)

Article 334 of the National Electrical Code (NEC) specifically addresses nonmetallic-sheathed cable, which includes Type NM (Nonmetallic Sheathed Cable), NMC (Nonmetallic Sheathed Cable for Mobile Homes), and NMS (Nonmetallic Sheathed Cable for Service Entrance). This section outlines the appropriate usage, installation methods, and the requirements for these particular types of cables, emphasizing their construction and application in residential and certain other installations. Type NM is commonly used in residential wiring because it offers flexibility and is relatively easy to work with, while also being cost-effective. The inclusion of NMC and NMS indicates that it applies to certain specialized applications, reinforcing the context of Article 334. Thus, this answer reflects the correct identification of types of cable expressly cited within the article. Other types of cables mentioned in the other choices fall under different articles or sections of the NEC, covering various applications not addressed in Article 334.
