Southwire 12/2 UF B Wire with Ground, 100 ft
Ort: Outdoor direct burial cable rated for underground installation without conduit. Conductors are annealed copper, with a PVC jacket for durability and corrosion resistance. This option is best for homeowners needing a compact 100-foot run to power outdoor fixtures such as lamp posts or small pumps. A potential limitation is shorter length for longer installations, where a longer reel may be required.
Best for: Small residential outdoor projects, quick deployments, and uncomplicated underground feeds. Choose this if you need a reliable, straightforward direct burial cable without extended lengths.
FIRMERST 12/2 UF Wire Outdoor Direct Burial Underground Feeder Cable 150ft
Specification highlights: UF‑B 12 AWG solid copper conductor with ground wire; 150 ft length; 600 volts; ETL-listed for direct burial; PVC jacket resists corrosion and UV exposure. This makes it suitable for longer outdoor runs to pumps, lights, and distant outbuildings, with robust durability in sun and moisture. A caution: longer cables may require careful trenching and routing to avoid damage in harsh terrain.
Best for: Long outdoor feeders and installations needing a substantial length without conduit. Choose this if your project requires more than 100 ft and you want ETL-listed direct burial readiness.
FIRMERST 12/2 UF Wire Outdoor Direct Burial Underground Feeder Cable 100ft
Header specs mirror 150 ft version with a 100 ft length, including ETL listing for direct burial and a PVC jacket that resists UV and moisture. The solid copper conductors ensure stable conductivity for outdoor lighting and irrigation projects. Limitations are similar to other UF-B products: longer deployments require careful burial planning and protection from physical damage.
Best for: Medium-length outdoor runs needing direct burial without conduit. Choose this if your project sits around 100 ft from the power source and you want a robust, UV-resistant jacket.
12/2 UF-B Wire 150 FT (Energeaster)
Features: 12/2 AWG solid copper with a PVC jacket; 150 ft length; direct burial capable; rated 600 volts; sunlight and moisture resistant. This option emphasizes durability in outdoor environments, suitable for lighting and pump installations. A potential limitation is that some installations may require strain relief or protective conduits in rocky or high-traffic areas.
Best for: Outdoor lighting and pump installations requiring a dependable, UV-resistant feeder with substantial length. Choose this if you need a straightforward 150 ft run in harsh outdoor conditions.
Wirenco 12/2 UF-B Wire, 500 Ft (Direct Earth Burial)
Highlights: 12/2 UF-B with direct earth burial capability; rated for 600 volts; 500 ft length; resistant to sunlight. This long-run option is ideal for larger outdoor projects where burying a lengthy feeder is necessary, such as farm buildings or multiple structures. Limitation: very long runs require careful installation planning to manage voltage drop and physical protection along the trench.
Best for: Large outdoor installations and distant outbuildings. Choose this if you need a single long reel to minimize splices and simplify burial work.
Buying Guide
Direct burial 12/2 with ground cables vary in length, jacket durability, and listed certifications. Consider these factors to pick the best match:
- Length needs: Match the reel length to your run to minimize splices and extensions.
- Jacket material: PVC jackets resist moisture and UV; ensure the jacket is rated for direct burial.
- Copper type: Solid copper conductors provide stable conductivity and mechanical strength for outdoor use.
- Voltage rating: Ensure the cable is rated for at least 600 volts, suitable for typical residential outdoor loads.
- ETL/UL listing: Look for certified direct burial listings to assure safety and compliance.
- Environmental considerations: For sun-exposed or moisture-prone areas, prioritize jackets with UV resistance and moisture resistance.
- Protection beyond burial: In rocky soils or high-traffic zones, consider conduit or protective sleeve where needed to prevent damage.
