THHN Wire

THHN wire is a type of electrical wire that is commonly used as building wire in residential and commercial constructions. The letters THHN stand for Thermoplastic High Heat-resistant Nylon coated, wire which describes the materials that the wire is made of.

The copper conductor of the THHN wire is covered with a thermoplastic PVC insulation that provides protection against moisture and abrasion. This insulation is also rated to withstand high temperatures, typically up to 90°C. In addition, the wire is also coated with a nylon jacket that provides further protection against wear and tear.

THHN wire is available in a range of sizes and colors, and it is often used for wiring control circuits, as well as for lighting and control wiring. It is also suitable for use in conduit, which is a pipe or tube that is used to protect and route electrical wires.
