SOUTHWIRE COMPANY #13059155 250′ 10/3 W/G UF Cable
This heavy-duty underground cable is designed for direct burial. It uses multi-strand copper to support 10 AWG conductors with a ground and is suitable for 220/240-volt applications. The construction emphasizes durability for long outdoor runs and versatile use in residential, commercial, and agricultural settings. Best for: projects requiring reliable underground power delivery over longer distances, such as outdoor lighting circuits or subpanel feeders. Caution: ensure proper burial depth and local code compliance for underground installations.
10/3 UF-B Wire, 150ft Direct Burial
This 150-foot option targets longer underground feeders with a 10/3 configuration and a dedicated ground. It emphasizes suitability for direct burial and outdoor power runs. Best for: projects needing a moderate length UF-B cable for outdoor feeders in yards or around structures. Limitation: setup depends on local burial codes and may require trenching and proper conduit planning in certain sites.
10/3 UF-B Wire – 100FT (YDDECW Store)
This 100-foot 10AWG/3 UF-B cable focuses on direct burial and outdoor reliability with a robust copper build. It notes RoHS compliance and a broad operating temperature range, which supports use in varied climates. Best for: customers needing a compact, short-run underground feeder with durable copper conductors. Better for: installations where RoHS compliance and temperature tolerance are priorities. Caution: ensure the burial method aligns with local electrical codes.
Wirenco 10/3 UF-B Wire (50Ft)
Wirenco offers a 50-foot UF-B direct burial option with 10/3 configuration. The listed features note color variation and a 600-volt rating, along with a 90°C heat capacity. Best for: small or temporary underground runs and retrofit tasks where a shorter, easier pull is advantageous. Limitation: color variation may affect visual matching with other components, so plan accordingly for visible installations.
8/3 UF-B Wire (100 FT)
This 8/3 UF-B option is built for higher-ampacity underground feeders. The 100-foot length makes it suitable for medium-range runs under driveways, lawns, or across lots. Best for: installations requiring greater conductor capacity than 10/3 in a direct burial context. Caution: verify compatibility with downstream equipment and local code requirements for 8 AWG conductors in underground runs.
Buying Guide
What matters most when choosing 10/3 UF cable?
Material quality and conductor composition affect durability and conductivity. Multi-strand copper designs generally offer better flexibility and reliability for underground pulls than solid cores. Look for direct burial suitability and a 600-volt rating for most residential and commercial outdoor projects.
How long should a direct burial UF cable last?
With proper burial depth and protection from moisture and physical damage, UF cables are designed for long-term underground service. Consider climate, soil conditions, and potential exposure to moisture, chemicals, or abrasion when estimating lifespan.
What installation considerations are important?
Key factors include burial depth, use of conduit where required by code, protection from physical damage (such as from lawn equipment), and adherence to local electrical permitting requirements. Short runs may benefit from easier handling, while long runs require careful routing and support.
What are common trade-offs among the options?
Longer cables offer flexibility for future expansion but can be harder to pull. Higher gauge (like 8/3 versus 10/3) increases amperage capacity but may be more expensive and heavier to handle. Color variation in some brands may require attention to identification and compatibility with existing systems.
How should I decide between UF and UF-B?
UF is intended for direct burial and is generally suited for outdoor direct burial without conduit in many cases. UF-B is a similar direct-burial rated cable but is typically used for feeders with more emphasis on outdoor and underground reliability. Check local codes to confirm whether conduit is required in your area before installation.
Installation quick-checks
- Confirm voltage requirements and ensure 600V rating or higher.
- Verify burial depth per local code and project type.
- Keep conductors dry and protected from moisture and abrasion.
- Use appropriate connectors and termination methods designed for UF/B cables.
Who should consider these top picks?
Contractors and DIY homeowners planning outdoor feeders, subpanel feeds, or yard-lit installations can benefit from the variety of lengths and gauges. Long-span options suit larger properties, while shorter runs work well for retrofit or limited-space projects. Agricultural settings may prefer robust, durable copper conductors for barn wiring or remote outbuildings.
FAQ
- What is 10/3 UF cable used for? – It is an underground feeder cable with three insulated conductors and a ground, suitable for outdoor, direct burial electrical runs.
- Can UF-B be buried directly without conduit? – In many cases, UF-B is designed for direct burial, but always verify local code requirements for burial depth and protection.
- What does 600V rating mean? – It indicates the maximum voltage the cable is designed to carry safely in typical residential and commercial outdoor installations.
- Is temperature rating important for underground cables? – Yes. A higher temperature rating helps ensure performance in extreme underground conditions and varies by product.
- Should I hire a professional for burial installations? – For complex runs or code-sensitive projects, professional electrical help ensures compliance and safety.
