Copkim 100′ 4-4-4-6 SER Aluminum Service Entrance Cable
Copkim’s 100-foot 4-4-4-6 SER cable uses a lightweight AA-8000 series compact stranded aluminum conductor. It includes three 4 AWG insulated conductors and one 6 AWG bare ground/neutral conductor, delivering stable power for residential panel feeders. The insulation handles up to 90°C, and the outer PVC sheath resists UV exposure, humidity, and abrasion for outdoor or indoor use. This configuration improves handling and routing through conduits compared to copper equivalent cables, making installation faster and easier.
The product supports above-ground feeder connections and panel terminations where a bare ground/neutral conductor is required. It’s designed for durable operation in various environments, while maintaining flexibility for tight spaces. Ideal for contractors who prioritize a balance of weight, performance, and long-term reliability.
Copkim 125′ 4-4-4-6 SER Aluminum Service Entrance Cable
The 125-foot Copkim option mirrors the 100-foot variant with identical 4-4-4-6 configuration, providing extended reach for longer runs between distribution panels and feeders. The combination of three insulated 4 AWG conductors and a 6 AWG bare ground/neutral conductor continues to emphasize flexible handling, reduced installation time, and strong weather resistance. The lightweight nature of the aluminum alloy helps simplify routing through conduits and trenches, particularly in commercial installations.
With the same 90°C insulation rating and UV-resistant outer sheath, this length is well-suited for exterior installations, underground conduit applications, or above-ground feeders where longer trench runs are common. As with all 4-4-4-6 ser cables, ensure correct terminations and ground bonding per local electrical codes.
Copkim 50′ 4-4-4-6 SER Aluminum Service Entrance Cable
This 50-foot option provides a compact solution for shorter runs or spaces where a shorter feeder length is necessary. The 4-4-4-6 arrangement remains the same, offering three 4 AWG insulated conductors plus a 6 AWG bare ground/neutral. The direct burial design benefits from the AA-8000 aluminum’s flexibility, making it easier to pull through conduits and adapt to service entrances near panels or outdoor disconnects. The 90°C insulation and UV-resistant sheath remain key durability drivers for outdoor installations.
MOOKEERF 6/3 Wire With Ground
MOOKEERF’s 6/3 NM-B copper cable provides a 6 AWG three-conductor arrangement with a grounded conductor. Built for indoor residential wiring, it uses pure copper conductors and a dual-layer insulation system with inner PVC insulation and an outer nylon jacket for mechanical protection. It’s rated for -10°C to 90°C and is suitable for outlets, switches, and other indoor loads. While not a 4 AWG product, it serves as a relevant nearby option when wiring needs align with 6 AWG conductors and ground in confined interior spaces.
Typical applications include branch circuits for lighting, receptacles, and some small appliances where indoor dry locations are guaranteed. The nylon outer jacket provides abrasion and chemical resistance, contributing to long service life in walls or conduits. Always verify local code requirements for NM-B installation in your building’s climate zone.
ARIZONA ELECTRICAL SOLUTIONS 50 Feet 6/3 Type NM-B Copper
This 50-foot NM-B copper cable provides a 6/3 configuration with a bare ground conductor, designed for indoor use. The jacket is a durable insulated nylon-PVC blend rated for 600 volts and RoHS compliant, aligning with common US residential wiring standards. While it uses 6 AWG conductors rather than 4 AWG, it remains a widely used option for dry indoor installations on branch circuits and subcircuits requiring reliable grounding and compliant insulation. Color-coded jackets aid identification during installation.
ARIZONA ELECTRICAL SOLUTIONS 40 Feet 6/3 Type NM-B Copper
This 40-foot NM-B option also uses a 6/3 copper configuration with ground and is intended for indoor use. The jacket is black and designed for dry interior installations. While not a 4 AWG product, it remains relevant for scenarios where a 6 AWG conductor setup is adequate for the load requirements. The product emphasizes compliance with indoor wiring standards and practical routing through walls and joists.
XMK 6/3 NM-B Wire With Ground
XMK offers UL-listed 6/3 NM-B copper cable with a 10 AWG ground, suitable for residential indoor use. It is designed for dry locations, including garages and basements, and supports loads on 120/240V circuits. The insulation is rated for -10°C to 90°C and RoHS-compliant, balancing safety and performance for interior installations where 6 AWG conductors meet the required amperage. This is a practical alternative when 4 AWG is not necessary or available.
50 Feet 6/3 Type NM-B Copper (Alternate)
This additional 6/3 NM-B copper option provides a compact choice for interior wiring with a ground conductor. It adheres to NM-B specifications, ensuring compatibility with typical residential receptacles, switches, and small circuits. While not 4 AWG, its 6 AWG conductors with a ground remain widely used in many homes for standard lighting and outlet circuits, and it may be a cost-effective match for projects with lower amperage demands.
Buying Guide: Key Purchase Considerations
- Conductor size and configuration: For 4 AWG needs, prioritize cables advertised as 4 AWG with an additional ground/neutral conductor. If 4 AWG options are limited, consider compatible 6 or 8 AWG NM-B options for interior applications, understanding that ampacity will differ.
- Insulation and temperature rating: Look for insulation rated to at least 90°C when used in outdoor or high-heat environments. A UV-resistant outer sheath adds durability for exposed runs.
- Conductor material: Aluminum ser conductors offer lighter weight and easier handling, while copper conductors provide higher conductivity. Aluminum is common for feeders, but verify compatibility with your panel and grounding requirements.
- Application environment: Indoor NM-B cables suit dry indoor locations; outdoor or underground runs require sheathed or SER-type cables with appropriate weather resistance and burial suitability.
- Grounding and bonding: Confirm that the ground conductor size and bonding method comply with national and local electrical codes. Bare grounds in SER cables simplify bonding in outdoor installations.
- Length and routing: Choose lengths that minimize splicing and simplify routing through conduits, joists, and panels. Longer runs may require thicker gauges or different cable types to maintain safe ampacity.
- Code compliance: Ensure all selected cables comply with NEC standards and local amendments. Check markings on the jacket for voltage rating, temperature rating, and compliance stamps.
- Installation environment: For wet or damp locations, select cables with moisture-resistant insulation and jackets. For buried runs, verify direct burial suitability and burial depth requirements.
- Cost and availability: Compare price over the required length and consider stock availability for project timelines. Aluminum SER cables are generally lighter and easier to install than copper equivalents in many scenarios.
