Nonmetallic-Sheathed Cable includes which types?

Nonmetallic-sheathed cable refers to a type of electrical cable that is widely used for residential and commercial wiring applications due to its versatility and ease of installation. The correct answer highlights the types included under nonmetallic-sheathed cable, specifically identifying NM (Nonmetallic Sheathed Cable), NMC (Nonmetallic Sheathed Cable for damp and wet locations), and NMS (Nonmetallic Sheathed Cable for special applications).

NM is commonly used in dry interior areas and is a staple in residential wiring. NMC is designed to provide additional protection under conditions that would normally expose wiring to moisture, making it suitable for areas like basements or outdoor structures that are not completely exposed to the elements. NMS serves specialized applications that may require additional considerations due to specific environmental factors or installation needs.

The inclusion of NM, NMC, and NMS in the correct answer emphasizes the range of nonmetallic-sheathed cables that meet distinct requirements and standards under the NEC, showcasing their respective properties and applications in wiring practices. This differentiation is important for electricians and designers to ensure that the appropriate type is selected based on the installation environment and code compliance requirements.
