Why this matters for your project
Using UF-B WG 14/3 solid copper is ideal when you need a simple, robust feeder for outdoor circuits. The three conductors plus ground support 120/240V feeds to exterior receptacles, sub‑panels, or outbuildings without the need for conduit in many installations. The solid copper conductors resist fatigue over long runs and reduce voltage drop compared to stranded alternatives over similar lengths. The combination of PVC insulation and a nylon jacket provides dependable moisture resistance and abrasion protection in sun‑drenched or wet environments.
Practical use cases
- Feed outdoor lighting circuits, receptacles, or small equipment directly from your main service panel
- Run power to sheds, workshops, or detached garages with a single continuous 250 ft run
- Underground connections to landscape features that require reliable 120/240V supply
Installation notes and best practices
- Plan burial depth and trenching according to local electrical codes; UF-B WG is designed for direct burial where permitted
- Protect the run from physical damage and sharp edges; maintain gentle bends to avoid conductor kinks
- Seal and protect terminations at boxes and devices with rated connectors and appropriate strain relief
- Avoid co‑locating this feeder with other utility lines in the same trench; separate as required by code
With its rugged construction, direct burial capability, and long 250 ft length, the Southwire 250 ft. 14/3 Solid Type UF-B WG Underground Feeder Cable is a practical, code‑conscious solution for bringing power where you need it—outdoors, underground, and reliably over the long haul.
