What is another name for nonmetallic sheathed cable?

Nonmetallic sheathed cable, commonly referred to as Romex cable, is widely used in residential electrical wiring. The name "Romex" comes from a brand of nonmetallic sheathed cable manufactured by Southwire Company, which has become synonymous with the product itself. This type of cable consists of insulated conductors encased in a flexible plastic sheath, providing protection against moisture and mechanical damage while being relatively lightweight and easy to handle.

Romex cable is designed specifically for use in dry residential environments and is suitable for various applications, including outlets, lighting, and power distribution. Its construction allows for easier installation in walls, ceilings, and floors, contributing to its popularity among electricians and builders.

The other options listed refer to different types of electrical wiring or conduits. Armored cable, for instance, has a protective metal sheath that provides additional durability and protection, which is not the case with nonmetallic sheathed cable. Electrical metallic tubing is a type of conduit made of metal, and conduit cable refers to cables that are protected within conduit systems. Thus, Romex cable distinctly identifies nonmetallic sheathed cable, making it the correct choice.
