Type NM cable is NOT permitted for use in which of the following locations?

Dry locations
Wet locations
Residential applications
Commercial applications

The correct answer is: Wet locations

Type NM cable, commonly known as non-metallic sheathed cable, is designed primarily for dry locations. This limitation is due to its insulation material, which can degrade or become damaged when exposed to moisture or wet conditions. Wet locations demand cables that are specifically rated for those environments, which typically have higher protection standards to ensure safety and functionality. In contrast, NM cable is extensively utilized in dry environments, including many residential and some commercial applications, making it an ideal choice for projects where moisture is not a concern. Understanding the specific applications and limitations of NM cable is crucial for compliance with electrical codes and ensuring safety in all installations.
