Stock Wire 6/3 UF-B Underground Feeder Wire - 100ft Cut

Overview

Stock Wire 6/3 UF-B Wire is designed as an underground feeder and branch circuit cable, ideal for running from an existing building to outdoor lighting, pumps, outbuildings, and other equipment. The assembly is rated for 600 volts and built to withstand outdoor exposure, including direct burial in appropriate conditions.

While the insulation is rated for 90°C in both dry and wet conditions, national electrical code guidelines limit ampacity to 60°C-based ratings for practical use. This cable can be buried directly or installed where it may face sunlight. When used as NM cable, it must adhere to NEC Article 334 requirements. These design considerations help practitioners plan installations with safety and compatibility in mind.

Key Features

• Annealed (soft) copper conductors ensure flexibility during pulls and reliable electrical contact.
• PVC insulation with nylon covering provides phase identification and added durability.
• Sunlight- and moisture-resistant gray PVC jacket supports outdoor exposure and long-term performance.
• Three 6 AWG conductors plus a 10 AWG ground deliver a robust three‑conductor path with a dedicated ground.
• Rated for 600 volts and an ampacity of 55 amps for end-use calculations in typical installations.
• Nominal dimensions of 1.223 inches by 0.361 inches and a weight of roughly 0.437 lbs per foot aid in handling and routing.
• Compliance with multiple standards (ASTM B3/B8, UL 83, UL 493, and NFPA 70) ensures alignment with industry expectations.

What This Means for Your Projects

• Direct burial and outdoor runs become feasible choices for outdoor lighting, irrigation, pumps, or支 various outbuildings when appropriate burial conditions are met.
• The jacket’s durability helps resist environmental factors like moisture and sun exposure, reducing maintenance needs in exposed locations.
• The color-coded insulation assists with quick identification of conductors during installation and future servicing.
