THW THN THHN Cable 1/0 2/0 3/0 4/0 AWG PVC Flexible Cable Single Core Copper Wire Nylon Jacket Cable

THHN cable is a single-conductor building wire widely used for power distribution and branch circuit wiring in commercial, industrial, and residential projects. The conductor is insulated with heat-resistant PVC and protected by a smooth nylon jacket, allowing easier pulling through conduit while providing additional resistance to wear and chemicals.

As one of the most commonly specified conductors in North American electrical installations, THHN wire is suitable for panel boards, control equipment, switchboards, lighting circuits, and feeder systems.

Available in a wide range of AWG and kcmil sizes, THHN wire helps contractors meet electrical code requirements while maintaining installation efficiency.
