FIRMERST 12/2 UF Wire Outdoor Direct Burial 100ft
FIRMERST’s 12/2 UF-B wire provides a solid copper conductor with a grounding wire, delivering reliable electrical conductivity for outdoor and indoor connections. The cable ships in a 100 ft length with an outer PVC jacket rated for direct burial. Its OD is approximately 5.6 by 11.8 mm, and it is rated for up to 600 volts, making it suitable for wet or dry locations. The jacket offers corrosion and UV resistance, supporting durable outdoor performance. This option is ideal for feeders to outdoor outlets, landscape lighting, or pumps where a buried path or trench is involved. The 12 AWG copper conductors aim to balance performance with ease of installation for homeowners and installers alike.
Southwire UF-B Underground Feeder Cable, 12/2 AWG 250 ft
Southwire’s UF-B 12/2 cable comes in a long 250-foot length, with conductors made of annealed copper and a PVC insulation jacket. The cable is designed for underground direct burial and is available with 2 or 3 conductors, with or without a ground wire. The jacket is color coded and nylon reinforced, adding durability in outdoor environments. This option suits feeders to outdoor lighting, post lamps, or other outdoor loads where a direct-burial installation is required. The use of annealed copper helps with ductility during installation, and the PVC insulation provides basic resistance to moisture and environmental exposure.

The listing notes its typical use cases in outdoor installations, reflecting a balance of robustness and flexibility for long runs across yards or landscapes. Its durable copper conductors support reliable current delivery for standard residential outdoor electrical circuits.
FIRMERST 12/2 UF Wire Outdoor Direct Burial 150ft
This FIRMERST 12/2 UF-B cable extends to 150 ft and uses a solid copper conductor with a ground wire. It is ETL-listed for direct burial and suitable for dry or wet locations, ensuring reliable performance in buried outdoor runs. The 600-volt rating matches typical residential and light commercial installations, while the PVC jacket offers UV and corrosion resistance. The product complements longer buried paths to outdoor outlets, lighting transformers, or irrigation controllers where a sturdy, buried feeder is required.
ZONEGRACE 12AWG 2-Conductor 12/2 Direct Burial Wire
ZONEGRACE offers a multipurpose 12/2 low-voltage cable suited for landscape lighting and other outdoor projects. This direct burial-grade wiring uses bare copper conductors and a heavy-duty jacket designed to withstand sun exposure, moisture, and physical wear. The 265-foot length supports extended runs for path lights, area lights, floodlights, and underwater lighting setups in specialty installations. It is positioned as a robust choice for outdoor lighting systems where direct burial capability and durable insulation are essential.
Buying Guide
When selecting a 12/2 direct burial cable, consider the following factors to ensure proper performance and safety:
- Conductor type: Copper conductors offer excellent conductivity and durability; stranded vs solid copper affects flexibility during installation.
- Burial readiness: Look for ETL-listed or UL-listed direct burial cables with a UV-resistant PVC jacket designed for moist or wet locations.
- Voltage rating: Most 12/2 UF-B cables are rated to 600 volts, which covers common residential and light commercial applications.
- Jacket durability: A jacket resistant to moisture, corrosion, sunlight, and abrasion extends service life in outdoor environments.
- Conductor configuration: 2-conductor with or without a ground is common; plan grounding needs based on local codes and load types.
- Length and routing: Match the cable length to the installation plan, allowing extra slack for fittings and future adjustments.
- Application fit: Low-voltage landscape lighting may use 12/2 low-voltage cable, while general feeders to outlets or pumps may require standard 12/2 UF-B wiring.
- Code compliance: Verify local electrical codes and permits for outdoor and burial installations to ensure safe, compliant wiring.
