FIRMERST 14/2 UF Wire Outdoor Direct Burial 100ft
FIRMERST’s 14/2 UF wire is a direct burial feeder with a solid copper conductor and a ground wire. It is rated for 600 volts and ETL-listed for direct burial in dry or wet locations. The PVC jacket offers UV resistance and corrosion protection, making it suitable for outdoor installations that require durable, weather-resistant power paths.
FIRMERST 12/2 UF Wire Outdoor Direct Burial 150ft
This 12/2 UF wire provides a longer direct burial run with a 150 ft length and 600-volt rating. It uses a PVC jacket that resists corrosion and UV exposure, ensuring reliable outdoor performance for feeders from main panels to exterior installations or outbuildings.
FIRMERST 12/2 UF Wire Outdoor Direct Burial Stranded Copper Cable 100ft
This 12/2 UF wire uses stranded copper conductors for added flexibility and ease of installation in outdoor settings. With a ground wire and a durable PVC jacket, it supports outdoor circuits and is ETL-listed for direct burial, suitable for dry or wet locations.
Cat 6 Direct Burial Ethernet Cable 1000ft UltraPoE
UltraPoE Cat 6 direct burial ethernet cable provides solid 23 AWG copper conductors, with up to 550 MHz bandwidth. It supports PoE, PoE+, and PoE++, enabling power delivery over Ethernet while maintaining stability for long outdoor runs. The gel-filled core enhances waterproofing, and the UV-resistant jacket protects against sunlight and weather.
trueCABLE Cat6A Direct Burial, Shielded FTP
trueCABLE’s Cat6A direct burial cable is shielded (FTP) to reduce EMI and cross-talk, suitable for outdoor installations with up to 750 MHz bandwidth. It supports PoE++ up to 100W and is ETL-listed. The pre-spooled 500-foot option offers convenient, tangle-free handling for professional deployments.
trueCABLE Cat6 Direct Burial 1000ft
This bulk Cat6 outdoor cable delivers 23 AWG bare copper conductors, 550 MHz bandwidth, and PoE++ support. It’s designed for direct burial with CMX-rated jacket and unshielded (UTP) configuration, offering a balance of performance and value for long outdoor runs in network installations.
Buying Guide
When choosing direct burial cables, consider these key factors to ensure safety, longevity, and performance:
- Application and rating: UF wires are for power feeders and should be selected by voltage and gauge (e.g., 14/2 or 12/2, 600V). Cat6 direct burial cables are for network installations with PoE support and budgeting for bandwidth needs.
- Conductor material: Solid copper offers low resistance and stable connections; stranded copper provides flexibility for complex pathways.
- Jacket durability: PVC jackets protect against moisture, UV exposure, and corrosion. UV resistance is important for above-ground or exposed burial areas.
- Waterproofing and burial method: Gel-filled cores and moisture barriers improve waterproofing for direct burial. Plan burial depth and whether conduit is used.
- Length and routing: Longer runs may introduce signal loss in network cables or voltage drop in power feeders. Match length to installation plans and local code requirements.
- EMI and shielding: For networks in electrically noisy environments, shielded options (FTP) help reduce interference and cross-talk.
- Code compliance: Ensure components are ETL-listed or UL-listed and suitable for direct burial according to local electrical codes and standards.
Across power and network cables, selecting a reputable brand with clear specifications helps ensure safety and dependable performance. For residential outdoor feeders, UF wires with robust jackets and appropriate gauge provide reliable power delivery. For outdoor networking where PoE is used, Cat6 direct burial cables with proper shielding and waterproofing support stable, long-distance connectivity. Consider installation conditions, future expansion plans, and local regulations as you decide between these options.
