Thermoplastic Insulated Wire and Cable

APPLICATIONS

THHWbuilding wire is intended for general purpose applications as defined by the USA National Electrical Code (NEC). THHW is permitted used in conduit and cable trays for services, feeders, and branch circuits in commercial or industrial new construction or rewiring for 600 volt applications. For applications requiring THHW, the wire is appropriate for use in dry locations at temperatures not to exceed 90˚Cor wet locations at temperatures not to exceed 75˚C.
