Southwire 500 ft. 10/1 Solid THHN Building Wire is a dependable, code-ready power path designed for demanding conduit runs and versatile indoor/outdoor applications. This single-conductor, solid 10 AWG copper wire brings together durable insulation, a rugged jacket, and practical length to streamline installations from the panel to the final fixture.
Key features that matter on every job site:
-
Solid copper conductor, 10 AWG for minimal resistance and stable current delivery on up to 30 amps, helping you keep circuits protected and efficient.
-
PVC insulation paired with a nylon jacket delivers excellent abrasion resistance, moisture protection, and long-term durability in challenging environments.
-
Direct burial capable and wet location rated design means you can rely on this wire for outdoor runs and areas exposed to moisture, with fewer concerns about environmental exposure.
-
600V voltage rating paired with a high 194°F (90°C) temperature rating supports a wide range of residential and commercial applications, from lighting circuits to feeders.
-
UL listed for safety and reliability, giving you confidence in compliance and performance.
-
UV resistant and green jacket for outdoor visibility and durable identification in complex installations.
-
500 ft length reduces splicing and inventory management, letting you complete larger runs with fewer joins and interruptions.
-
Indoor and outdoor use with single conductor design makes it ideal for conduit-fed projects, service panels, equipment hookups, and general wiring where a solid, protected conductor is required.
Why this wire stands out in real-world projects
Electricians and facility managers choose the Southwire THHN building wire for its blend of reliability and practicality. The solid 10 AWG copper core minimizes voltage drop on longer runs, while the PVC insulation and nylon jacket shield against moisture, abrasion, and everyday wear in basements, crawlspaces, and outdoor conduits. The green jacket adds quick visual identification on crowded job sites, helping you distinguish this conductor from others in a complex system.
Ideal use cases
- Feeder and branch circuits in both new builds and renovations that require durable, UL-listed THHN in conduit.
- Outdoor equipment hookups, panel feeders, and lighting runs where direct burial and wet-location performance are beneficial.
- Industrial or commercial installations where environmental exposure, UV resistance, and robust insulation are priorities.
- Projects demanding a long spool to minimize field splices and downtime during installation.
