What is nm cable?

NM cable, also known as non-metallic sheathed cable, is a type of electrical cable commonly used for residential wiring in the United States. It consists of two or more insulated conductors (wires) encased in a plastic outer sheath.

NM cable is typically used for general indoor electrical wiring applications, such as lighting, outlets, and appliances. It is not suitable for use in wet or damp areas, as the plastic sheath is not waterproof.

NM cable comes in various sizes, with the most common being 14, 12, and 10 gauge. The cable is color-coded for easy identification, with 14 gauge typically being white, 12 gauge yellow, and 10 gauge orange.

When installing NM cable, it is important to follow local electrical codes and regulations to ensure safety and compliance. It is also recommended to use proper tools and techniques for stripping and connecting the wires to prevent any hazards.
