What type of cable would be appropriate for use in damp locations while resisting mold growth?

Type NM
Type UF
Type NMC
Type MC

The correct answer is: Type NMC

Type NMC cable, also known as non-metallic sheathed cable, is specifically designed for use in damp locations and has enhanced resistance to mold growth. This type of cable features a water-resistant insulation layer that helps prevent the ingress of moisture, making it suitable for environments where dampness is present. The additional protective qualities of NMC cable support compliance with electrical codes that specify requirements for damp locations, ensuring safety and durability. In comparison, Type NM cable is not suitable for damp locations as it lacks water-resistant features, which can lead to potential safety hazards in areas with moisture. Type UF cable is better suited for underground or wet locations but may not be as resistant to mold compared to NMC. Type MC cable, while versatile, generally does not offer the same level of moisture resistance needed specifically for damp locations and may require additional considerations for mold resistance. Therefore, NMC cable is the most appropriate choice that balances moisture exposure with mold growth resistance.
