NASSAU 40′ 2/0-2/0-2/0-1 SER Aluminum Service Entrance Cable
This Nassau Electrical Supply SER cable is engineered for service entrance applications with four conductors, including three insulated 2/0 conductors and a final 1/0 bare conductor. Rated for 600 volts and compatible with wet or dry locations, it supports above‑ground setups and panel feeders. The 40‑foot length provides a practical option for smaller residential or light commercial installs where a compact run is needed.
NASSAU 100′ 2/0-2/0-2/0-1 SER Aluminum Service Entrance Cable
This 100‑foot Nassau SER cable continues the same four‑conductor configuration (2/0-2/0-2/0-1) with aluminum conductors, suitable for longer service runs into panels or meters. Its longer length can reduce splices and simplify routing in larger properties, while maintaining the same 600‑volt rating and suitability for wet or dry locations.
Nassau Electrical Supply 90′ SER Aluminum Service Entrance Cable
This 90‑foot Nassau option offers the same four‑conductor setup (2/0-2/0-2/0-1) with aluminum conductors, designed for robust outdoor and indoor service runs. Its length makes it a versatile middle‑ground choice when routing allows for a longer cable than the 40‑foot option but shorter than a full 100‑foot run, with a 600V rating suitable for service entrances.
Wirenco 2/0-2/0-2/0-1 SER Aluminum Service Entrance Cable (20 Foot Cut)
Wirenco’s 20‑foot cut SER cable is ideal for tight installations where a short run is needed to reach a panel or meter. It’s rated for 600 volts and 90°C for use in both wet and dry locations, making it a flexible choice for above‑ground service entrances, panel feeders, and branch circuits. The UL 854 listing confirms compliance with industry standards for SER cables used in service entrances.
Wirenco 2/0-2/0-2/0-1 SER Aluminum Service Entrance Cable (40 Foot Cut)
This 40‑foot Wirenco SER option matches the standard 2/0-2/0-2/0-1 conductor configuration for SER cables used in service entrances. It’s rated at 600 volts and 90°C, suitable for both wet and dry locations, and designed for above‑ground applications. The length balances reach and ease of routing in mid‑size properties and installations requiring a longer run than the 20‑foot variant.
Wirenco 2/0-2/0-2/0-1 SER Aluminum Service Entrance Cable (30 Foot Cut)
This 30‑foot Wirenco option provides a compact length for installations with limited space. It maintains the standard 2/0-2/0-2/0-1 conductors and is rated for 600 volts and 90°C in both wet and dry locations. Ideal for efficient routing to a panel or meter without unnecessary excess cable, it supports reliable service entrance connections.
Buying Guide
Key considerations for selecting 150 amp SER Cable
When choosing a 150 amp SER cable, assess conductor material, insulation rating, and the installation environment. Aluminum SER cables are commonly used for service entrances due to their balance of cost and conductivity. Ensure the cable is rated for 600 volts and approved for wet or dry locations (UL 854). Confirm conductor sizes (commonly 2/0 conductors with a final smaller wire) and the number of conductors to match your meter base and panel configuration.
Length and routing are practical factors. Shorter runs reduce voltage drop concerns on long lines, while longer runs minimize splices and simplify routing around obstacles. Verify panel and meter clearance, as well as building codes in your jurisdiction. A properly rated SER cable should be used with compatible lugs and terminations rated for aluminum conductors to ensure a safe, durable connection.
Material and safety considerations
Aluminum SER cables require careful handling to prevent damage to insulation and corrosion at terminations. Use anti-oxidation compounds where recommended and ensure proper torque on connectors. For outdoor or underground routes, protect cables from physical damage and moisture exposure. Document compliance with local electrical codes and utility requirements to avoid installation issues during inspections.
Versatility is another factor. Some options are cut to specific lengths, which can reduce waste and simplify installation planning. Consider future expansion or rework when selecting a length, especially in commercial settings where panel configurations may evolve over time.
