125′ 4-4-4-6 SER Aluminum Service Entrance Cable
Best for longer runs with weight and flexibility in mind. This 125 ft option uses three 4 AWG insulated conductors and one 6 AWG exposed neutral/ground wire, meeting standard power transmission needs for distribution panel feeders in residential or commercial projects. It features a 90°C heat-resistant sheath and a sun-resistant PVC outer jacket for outdoor or indoor use. Best for electricians planning a mid-to-long feeder run.
Who it’s best for: contractors and homeowners tackling longer exterior or attic runs where ease of pulling through conduit matters. Why selected: it combines standard specification compliance with a lighter, flexible aluminum conductor.
Caution: verify conduit spacing and bend radii to avoid any potential insulation damage during installation.
75′ 4-4-4-6 SER Aluminum Service Entrance Cable
Best for projects with limited run length where a compact, flexible aluminum feeder is advantageous. The 75-foot option maintains the same three 4 AWG insulated conductors and a 6 AWG ground wire, delivering stable power transmission suitable for smaller homes or light commercial setups. It’s easier to handle in tight spaces and still supports outdoor installations with a UV-resistant sheath.
Who it’s best for: installers needing a shorter length to minimize waste and simplify routing. Why selected: strong balance of length, weight, and installation simplicity.
Caution: ensure the route allows safe access for future maintenance and does not require excessive pulling through narrow conduits.
150′ 4-4-4-6 SER Aluminum Service Entrance Cable
Best for longer indoor or outdoor runs where a longer continuous feeder is needed. The 150-foot option shares the standard 4-4-4-6 configuration and uses AA-8000 compact stranded aluminum alloy conductors for flexibility. It supports high heat resistance and weather resistance with a durable outer sheath.
Who it’s best for: projects requiring substantial reach between panels or meters. Why selected: a longer run without sacrificing installer-friendly flexibility.
Caution: check local code requirements for outdoor installations and ensure proper burial or routing practices for above-ground feeders.
50′ 4-4-4-6 SER Aluminum Service Entrance Cable
Best for short-run installations where ease of handling matters most. The 50-foot option adheres to the 4-4-4-6 configuration, featuring a lightweight design that simplifies routing in compact spaces or basements. It’s suitable for service entrances that require quick setup with less length to manage.
Who it’s best for: electricians and DIY setups that require quick, tidy runs in tight spaces. Why selected: greatest ease of handling in a short length while maintaining standard wiring specs.
Caution: short runs may not accommodate future expansion or re-routing without additional cabling.
NASSAU ELECTRICAL SUPPLY 100′ Nassau 4-4-4-6 SER Aluminum Service Entrance Cable
Best for homeowners or contractors who prefer a brand-backed option with a standard length. The Nassau 100′ Nassau 4-4-4-6 SER cable lists wire size as 4-4-4 AWG with a 6 AWG ground and aluminum conductor. It’s designed for straightforward service entrance installations with conventional specs.
Who it’s best for: buyers seeking a brand-name option with a mid-length run. Why selected: predictable, standard configuration for typical panel feeders.
Caution: verify that the product’s exact construction aligns with your local electrical code and panel requirements before use.
Buying Guide
What is 4-4-4-6 SER cable and where is it used?
4-4-4-6 SER cable is a service entrance feeder with three insulated conductors of 4 AWG and a 6 AWG exposed neutral/ground pair. It’s commonly used to connect outdoor service panels or feeders to distribution panels in residential or light commercial projects. Aluminum conductors offer lighter weight and easier pulling through conduits compared with copper, while maintaining adequate current-carrying capacity under normal conditions.
Material and insulation considerations
Look for AA-8000 series compact stranded aluminum alloy conductors for flexibility. A 90°C rated insulation helps support higher temperature operation, and a UV- and weather-resistant outer sheath protects against humidity, abrasion, and sun exposure in outdoor installations.
Length, routing, and installation tips
Choose the length to minimize waste while accommodating planned routing. Long runs should consider conduit bends, burial requirements if needed, and accessibility for future maintenance. For above-ground installations, verify that the sheath markings (such as 600V Type SE Style R) align with code expectations.
Safety and code considerations
Always confirm with local electrical codes and permit requirements. Ensure proper separation from other wiring, avoid sharp edges on conduit, and follow safe handling practices when bending and pulling cable. When in doubt, consult a licensed electrician.
Comparison snapshot
- Best for long runs: 125′ or 150′ options due to extra length while preserving flexibility.
- Better for tight spaces: 50′ or 75′ options due to shorter, lighter cable.
- Brand-backed option: Nassau 100′ for brand familiarity and standard specs.
FAQ
- What does 4-4-4-6 mean in SER cable?
It describes three 4 AWG insulated conductors plus one 6 AWG exposed neutral/ground conductor in the cable assembly.
- Is aluminum SER cable suitable for outdoor use?
Yes, when the outer sheath is UV-resistant and rated for exterior exposure, but verify local codes for outdoor installations.
- Which length should I choose?
Pick length based on your run distance and installation plan. Longer runs reduce joins but may require more conduit planning.
- Can I pull this cable through existing conduits?
Yes, the AA-8000 aluminum conductors are designed to be flexible, which facilitates pulling through conduits, but ensure conduit diameter and bend radii meet code requirements.
- What is the best option for a first-time installer?
Start with a shorter length (50 ft or 75 ft) to practice routing and then scale up for longer runs.
- Do all 4-4-4-6 cables have the same construction?
They share the same basic configuration, but minor differences may exist in insulation rating, sheath material, and printed specifications.
