2 Product Overview
The THHN 10 AWG building wire is a UL-certified single-conductor copper wire designed for 30A circuits and higher-load applications in commercial, industrial, and residential electrical systems. It complies with UL 83 (Thermoplastic-Insulated Wires) and UL 1063 (Machine-Tool Wire) standards.
The soft annealed bare copper conductor provides superior electrical conductivity with low DC resistance. The 10 AWG size is commonly specified for electric water heaters, AC units, ovens, and other high-load appliances requiring 30A circuit protection.
The PVC insulation with nylon (polyamide) jacket delivers reliable dielectric strength and robust protection against abrasion, moisture, oil, and chemicals. The smooth nylon surface facilitates efficient pulling through conduit runs, reducing installation time and labor costs.
Manufactured to rigorous quality standards under the management of SORIVO, each batch undergoes conductor resistance, insulation integrity, and dimensional testing. Rated for 600V at 90°C dry / 75°C wet with VW-1 flame rating. For detailed company information, please visit sorivocable.com/about-us/.
3 Key Features
UL 83 & UL 1063 Certified
Fully compliant with UL 83 and UL 1063 standards, ensuring acceptance across North American electrical codes and inspections.
High-Purity Copper Conductor
Soft annealed bare copper with low DC resistance minimizes voltage drop and energy loss in 30A circuit applications.
PVC + Nylon Dual Protection
PVC insulation provides robust dielectric strength, while the nylon jacket adds abrasion, moisture, and chemical resistance.
Easy Conduit Pulling
Low-friction nylon surface reduces pulling tension, preventing jacket damage during installation through long conduit runs.
VW-1 Flame Retardant
Rated VW-1 per UL 1581, providing flame propagation resistance for enhanced fire safety in building applications.
30A Ampacity Rating
Rated for 30A at 75°C, making it the standard choice for high-load circuits including water heaters, AC units, and ovens.
Wide Color Selection
Available in 11 colors for convenient phase identification and circuit tracing during installation and maintenance.
Flexible Stranded Construction
19-strand Class B construction offers flexibility for routing in confined spaces while maintaining long-term mechanical integrity.
