OVERVIEW

THHN Wire

THHN wires have a thin flame-resistant PVC insulation that is covered by an abrasion-resistant nylon jacket. THHN wires are suitable for applications up to 90°C in dry locations and 75°C in wet conditions. Although THHN wire can perform in high temperature environments, you must correct the wire's ampacity at high ambient temperatures and when bundling cables together in a raceway or conduit.

The maximum voltage rating of the THHN cable is 600 volts. All THHN cables meet the UL 83 standard for safety thermoplastic-insulated wires and cables as well as the UL 106 Standard for safety machine-tool wires and cables.
