Nassau 100′ Nassau 4-4-4-6 SER Aluminum Service Entrance Cable
Brand: Nassau Electrical Supply. Wire Size: 4-4-4 AWG. Ground Size: 6 AWG. Conductor Material: Aluminum. This 100-foot coil is designed for above-ground service entrance installations, delivering a robust aluminum conductor rated for 600 volts and 75 amps. The 4-4-4-6 configuration supports multi-conductor runs, reducing space in conduit and simplifying pulls in longer service routes. It is suitable for wet and dry locations, which makes it versatile for outdoor and indoor use where weather exposure is a factor. The aluminum construction provides good conductivity with resistance to corrosion, and the 6 AWG ground size helps ensure proper fault clearance.
Nassau 50′ Nassau 4-4-4-6 SER Aluminum Service Entrance Cable
This 50-foot option mirrors the 100-foot version with the same 4-4-4-6 AWG aluminum configuration and 6 AWG ground. Its shorter length provides flexibility for mid-length service runs or upgrading smaller homes without excessive waste. Rated for 600V and 75A, it remains suitable for above-ground installations in both wet and dry environments. The aluminum conductor offers reliable performance with the manageability of a shorter reel for easier handling and installation in tight spaces.
Wirenco 4-4-4-6 SER Aluminum Service Entrance Cable (50FT Cut)
Brand: Wirenco. This 50-foot cut version emphasizes ease of installation with a shorter reel. It is rated for 600 volts and 75 amps, suitable for above-ground service entrances. The cable is designed for use in both wet and dry locations, providing flexibility for outdoor feeders and indoor runs. Aluminum conductors reduce weight compared to copper while maintaining adequate conductivity for service entrances. The cut length helps contractors avoid excess waste while meeting project specifications.
Wirenco 4-4-4-6 SER Aluminum Service Entrance Cable (75FT Cut)
This 75-foot Wirenco option mirrors the 50-foot cut variant with a longer reach for broader service runs. It carries the same 600V and 75A rating and is suitable for both wet and dry locations. The aluminum construction provides a balance of flexibility and durability for above-ground installations. It is designed for straightforward pulling and handling, especially in projects where conduit paths require extra length without joints or splices.
Nassau Electrical Supply 75′ Nassau 4-4-4-6 SER Aluminum Service Entrance Cable
Brand: Nassau Electrical Supply. Length: 75 ft. Wire Size: 4-4-4 AWG. Ground Size: 6 AWG. Conductor Material: Aluminum. This variant extends the available lengths while preserving the same conductor count and insulation configuration. It is optimized for slightly longer runs in larger homes or small commercial spaces that require a robust aluminum SER cable with standard 600V/75A ratings. The longer pull length can reduce the need for splices, aiding in a cleaner, safer installation for service feeders exposed to outdoor elements.
Buying Guide: Key Purchase Considerations
When shopping for 4-4-4-6 SER aluminum service entrance cable, consider these factors to ensure an appropriate match for your project:
- Conductor material and finish: Aluminum is lighter and often more affordable than copper, but verify that the insulation and jacket meet local code requirements and are rated for wet or dry locations as needed.
- Voltage and ampacity: Most 4-4-4-6 SER cables are rated for 600V and 75A. Confirm your service panel and load calculations to avoid undersizing.
- Conductor arrangement: The 4-4-4-6 configuration indicates four conductors plus a ground, with the ground wire sized at 6 AWG. This affects both insulation thickness and installation clearance in conduits.
- Length and waste: Choose lengths that minimize splices and waste. Cut-length options can simplify handling but may affect pricing and availability.
- Environment and location: For outdoor or damp locations, ensure the jacket and insulation are rated for exposure to moisture, UV, and temperature variations.
- Brand and supplier reliability: Nassau Electrical Supply and Wirenco are common choices with multiple length options. Verify warranties and compatibility with local electrical codes.
- Installation considerations: Longer runs may require careful pulling tensions, bend radii, and conduit routing to prevent damage to insulation and conductors.
Comparative Considerations: Aluminum SER vs Other Alternatives
For service entrances, aluminum SER cables provide a practical balance of weight, cost, and performance compared with copper SER cables. Aluminum offers sufficient conductivity for most residential and light-commercial feeders, but installers should account for thermal expansion, corrosion resistance, and termination practices. When choosing between brands like Nassau Electrical Supply and Wirenco, consider documented voltage ratings, conductor gauge suitability, and approved use cases for wet or dry environments. If project constraints include very long runs, availability of lengths, or specific local code interpretations, consult with a licensed electrician or electrical inspector.
In summary, the selected 4-4-4-6 aluminum SER options deliver consistent performance across varying lengths and locations. They provide reliable ampacity and voltage ratings suitable for typical service entrances while offering practical choices for coastal, humid, or outdoor installations where aluminum conductors are advantageous. Always verify product approvals and compatibility with your service panel and local regulations before purchase.
