10/3 UF-B Wire 100FT 100% Pure Copper 10AWG 3 - Direct Burial Cable

In this review the 10/3 UF-B Wire 100FT is evaluated as a practical heavy-duty cable for outdoor and underground projects. It is aimed at homeowners, landscapers, and small contractors who need a durable, direct-burial feeder without extra conduit. The single biggest reason to buy is its combination of 10AWG/3 copper conductors and a full 10AWG ground in a PVC jacket rated for 600V, which makes it a straightforward, cost-saving option for outdoor circuitry where moisture, sun, and variable temperatures are concerns.

Key Features

• 10AWG/3 configuration: Provides robust current capacity and includes a full 10AWG ground for safer underground feeder runs.
• 600V rated: Suitable for a wide range of residential and light commercial outdoor power needs without voltage limitations in typical installations.
• Direct burial ready: Engineered to be buried directly in the ground, eliminating the need for conduit and reducing material and labor costs.
• Wide temperature range: Operates from -10C to 105C, maintaining flexibility and performance in both freezing and hot conditions.
• Durable PVC jacket: The jacket is waterproof and sunproof to resist moisture, UV exposure, and physical wear in outdoor settings.
• RoHS compliant: Free from listed hazardous substances to meet safer material standards.

Who It's For

This cable is best for homeowners installing landscape lighting, outdoor outlets, or small solar ground-mounted systems where a direct-burial feeder simplifies the job. Its flexibility and ease of stripping make it a good pick for DIYers and electricians who want a ready-to-bury solution that handles damp or corrosive locations.

Those who should look elsewhere include projects requiring conduit for mechanical protection, runs exceeding local code allowances for direct-burial without additional protection, or installations needing stranded conductors for extreme flexibility; for such needs a different cable type or conduit-protected wiring may be more appropriate.

Pros & Cons

Pros

• Good wire quality and solid copper conductors that deliver reliable conductivity for outdoor feeders.
• Easy to work with and flexible enough for bends and routing during installation.
• Direct burial design saves on conduit costs and installation time.
• Durable PVC jacket resists water, sun, and temperature extremes for long-term outdoor use.

Cons

• Not stranded conductors, which some installers prefer for maximum flexibility in tight bends.
• Direct burial does not replace the need to confirm local code requirements for deeper or protected runs in certain areas.
