Introduction
General purpose building wire for services, feeders and branch circuits.
Temperature rating not to exceed:
THHN/THWN: 90°C dry and dump, 600V
THHN/THWN: 75 °C wet or in oil, 600V
THWN-2: 90°C Dry, wet or in oil,600V
THHN conductors are primarily used in conduit and cable trays for services, feeders, and branch circuits in commercial or industrial applications as specified in the National Electrical Code. Voltage for all applications is 600 volts.
THHN/THWN-2 Conforms to following standards:
UL83 for Thermoplastic Insulated Wire and Cables(THHN/THWN-2)
UL758 for Appliance Wiring Materials(AWM)
UL1063 for Machine Tool Wire(MTW)(Stranded Conductor Only).
