What is a common characteristic of Type NM cable?

Type NM cable, also known as non-metallic sheathed cable, is commonly used in residential wiring applications, making it the correct choice. This type of cable is specifically designed for dry, indoor locations and is ideal for light and medium electrical loads typically found in homes. It consists of two or more insulated conductors and a bare ground wire, all encased in a non-metallic sheath, which provides protection without adding significant weight or bulk.

The design of Type NM cable, with its non-metallic sheathing, makes it unsuitable for outdoor use, as it lacks the necessary protection against moisture and environmental exposure. It also does not feature a metal sheath, as seen in different cable types such as Type AC or MC cables, which are used in varying environmental conditions. Furthermore, NM cable is not designed to withstand high temperatures, making it unsuitable for applications requiring high-temperature ratings. Thus, its primary focus remains on residential and light commercial applications where safety and functionality are prioritized within a controlled indoor environment.
