Nonmetallic-Sheathed Cable includes which types?

Nonmetallic-sheathed cable is specifically designed for residential and other light-duty applications, and it includes cable types that are characterized by their nonmetallic insulation. The correct types that fall under this category are NM (Nonmetallic Sheathed Cable), NMC (Nonmetallic Sheathed Cable with moisture-resistant sheathing), and NMS (Nonmetallic Sheathed Cable for special applications).

These types are intended for specific installations and have different characteristics suited to their use cases, such as being moisture-resistant or designated for specific environments, making them an important aspect of electrical wiring choices in buildings.

In contrast, other options include types of cable that serve different purposes or are made of different materials, such as metal conduit or armored cable, which do not fit under the classification of nonmetallic sheathed wiring. Thus, the understanding of the specific attributes and applications of NM, NMC, and NMS clarifies why they are categorized together under nonmetallic-sheathed cable.
