2 Product Overview
The THHN 14 AWG building wire is a UL-certified single-conductor copper wire designed for general-purpose electrical wiring in commercial, industrial, and residential applications. It meets the requirements of UL 83 (Thermoplastic-Insulated Wires) and UL 1063 (Machine-Tool Wire), ensuring compliance with North American electrical codes.
The soft annealed bare copper conductor provides excellent electrical conductivity with low DC resistance. Available in both solid and stranded (Class B 19-strand) constructions, the stranded variant offers enhanced flexibility for installations requiring tighter bends or frequent movement.
The PVC insulation combined with a nylon (polyamide) jacket delivers superior protection against abrasion, moisture, oil, and chemicals. The nylon jacket also provides a low-friction surface that simplifies pulling through conduit runs, reducing installation time and labor costs.
Manufactured to rigorous quality standards under the management of SORIVO, each batch is tested for conductor resistance, insulation integrity, and dimensional compliance. The wire is rated for 600V applications at operating temperatures up to 90°C dry / 75°C wet, with a VW-1 flame rating for added safety.
