Merriway Bulk Hardware BH01442 Earth Cable

This single-core round earth cable is a standard 6491X rated product designed for reliable grounding. Supplied as a 10-metre cut, it features a bright yellow and green insulation for easy identification. It is suitable for projects requiring a dedicated earth conductor and is commonly used in consumer electrical installations where a compact length is adequate. The insulation and construction emphasize ease of handling and consistent performance in typical indoor and controlled outdoor environments.
Stock Wire 10/2 UF-B Underground Feeder Cable (50ft)

The 10/2 UF-B cable uses annealed copper conductors designed for wet or corrosive indoor locations and for direct burial outdoors. The 50-foot cut length makes it suitable for shorter runs or tight installations where a straightforward underground feeder is needed. The design emphasizes durability in underground or damp environments, with a focus on flexible, easy-to-handle conductors that resist moisture and environmental exposure.
Stock Wire 10/3 UF-B Underground Cable (100ft)

This 10/3 UF-B cable features three annealed bare copper conductors, designed for indoor wet or corrosive locations and outdoor direct burial. The 100-foot length supports longer runs, reducing the need for splices. It is built to withstand sunlight and moisture exposure, making it suitable for exterior installations where a robust underground feeder is required alongside a reliable grounding path.
Stock Wire 10/2 UF-B Underground Cable (75ft)

This 10/2 UF-B offering uses annealed copper conductors and is suitable for indoor wet or corrosive environments, with outdoor suitability for direct burial. The 75-foot length provides a mid-range option for feeders or earth-grounding runs where standard 10 AWG conductors are adequate for the expected load and protective duties.
Wirenco 10/2 UF-B Underground Cable (100Ft)

Wirenco’s 10/2 UF-B cable uses annealed copper conductors and is rated for direct burial outdoors, including exposure to moisture. The 100-foot cut is well-suited for longer feeder runs, with a focus on reliability in wet or corrosive environments. This cable supports safe grounding along with earth burial requirements in appropriate installations.
Nassau Electrical Supply 100′ 10-3 UF-B

This solid 100-foot 10-3 UF-B cable is designed for underground direct burial and outdoor use up to 600V. The larger size and three conductors provide flexibility for feeders requiring a balanced phase arrangement, with specifications emphasizing robust insulation and resistance to environmental exposure. It is suitable for long runs and direct burial installations where a reliable earth path is essential.
Stock Wire 10/3 UF-B Underground Cable (75ft)

This 10/3 UF-B option offers three annealed copper conductors for indoor wet or corrosive environments while remaining suitable for outdoor direct burial. The 75-foot length makes it a practical choice for residential feeders or small commercial runs, providing reliable grounding and protective capabilities for buried installations.
Wirenco 10/3 UF-B Underground Cable (100Ft)

Wirenco’s 10/3 UF-B cable features a heat capacity rating of 90 degrees C and is rated for 600 volts, with an allowable ampacity of 30 amps. This makes it a robust option for outdoor direct burial and long feeders with direct burial demands, ensuring dependable grounding across longer distances while maintaining conductor integrity under outdoor conditions.
Buying Guide: Key Purchase Considerations
When selecting an earth or UF-B cable for 10mm class requirements or equivalent, consider the following:
- Voltage rating and ampacity: Ensure the cable’s voltage rating and causable ampacity align with the planned load and local electrical codes. Outdoor direct burial may demand higher protection ratings and weather resistance.
- Conductor size and color: Verify whether 10 AWG (or equivalent) and the conductor count (2 or 3) match your installation’s grounding and feeder needs. Color-coded insulation improves safety and maintenance readability.
- Insulation and jacket material: Select cables with durable insulation suitable for moisture, UV exposure, and direct burial. Some products emphasize sunlight resistance and moisture tolerance, reducing degradation risk.
- Installation length and splicing: Longer runs reduce the need for splices but require careful routing to avoid damage. Plan support points, burial depth, and protection along the path.
- Indoor vs. outdoor use: Indoor wet locations and corrosive environments require flexible, corrosion-resistant conductors and robust jackets. Outdoor direct burial demands additional environmental protection.
- Standards and compatibility: Look for compliance with standard references (e.g., 6491X) or other recognized specs. This helps ensure compatibility with existing electrical systems and code requirements.
- Durability vs. cost: Higher durability cables may carry a premium, but can offer long-term reliability in harsh environments, reducing future maintenance costs.
Choosing the right earth or UF-B cable requires balancing length, environment, and load considerations. The options above provide a range of lengths and configurations to support typical grounding and feeder installations while maintaining compliance with standard electrical practices.
