C
The type of wire that must be used in damp locations is NMW (Non-Metallic Wet-rated) wire.
NMW wire is specifically designed to be used in damp or wet locations. It is made with moisture-resistant insulation and is suitable for underground applications. NMW wire can be used in outdoor locations, such as for landscape lighting, or in indoor locations where moisture is present, such as basements, bathrooms, and laundry rooms.
NMD (Non-Metallic Dry-rated) wire, LVT (Low Voltage Thermostat) wire, and BX (Armored Cable) are not recommended for use in damp locations because they do not have adequate moisture protection. NMD wire is suitable for indoor use only and cannot be used where it may be exposed to moisture. LVT wire is specifically designed for low voltage thermostat applications and is not appropriate for damp environments. BX cable is suitable for dry locations only and should not be used where it may be exposed to moisture.
