Wire labeled THW has which characteristics?

Wire labeled THW has which characteristics?

• A. Thermoplastic insulated, heat resistant, damp and wet location
• B. Thermoplastic insulated, heat resistant, dry location
• C. Thermoset insulated, heat resistant, damp location
• D. Rubber insulated, damp and wet location

Answer: (A)

THW indicates a thermoplastic insulation that is heat resistant and water resistant, with the W signifying suitability for wet locations. This means the conductor is designed to perform in moist or damp environments and is not restricted to dry locations. The thermoplastic insulation distinguishes it from rubber-insulated or thermoset-insulated conductors, which are described by different designations. So this wire is appropriate for damp and wet locations due to its plastic insulation and water resistance, unlike options that imply rubber or thermoset insulation or dry-location use.
