Solid THHN Wire

Solid THHN wire is a dependable copper building wire used for grounding, branch circuits and general electrical wiring. Its single-conductor construction maintains its shape during installation and provides a secure connection at compatible terminals and devices.

THHN wire features durable thermoplastic insulation with a nylon outer jacket that helps resist heat, moisture, oil and abrasion. Available conductor colors support circuit identification and organized wiring within conduit, panels, cabinets and equipment assemblies.

Solid copper THHN wire is commonly installed in commercial buildings, telecom shelters, breaker panels, power supplies, remote radio units and industrial equipment. It supports new electrical construction, wireless-site deployments, equipment additions and maintenance work when installed according to applicable electrical codes.
