Wirenco 2-2-2-4 SER Aluminum Service Entrance Cable (75FT Cut)

Wirenco’s 2-2-2-4 SER aluminum service entrance cable is rated for 600 volts and 100 amps, designed for above-ground use in both wet and dry locations. The 75-foot cut length provides flexibility for service runs to panels or meters, and the construction supports common residential and light commercial installations.
FairySandy 50′ 1-1-1-3 SER Aluminum Service Entrance Cable

This FairySandy package uses 1 AWG conductors with a 3-conductor plus ground configuration and a 3 AWG bare ground wire, all rated at 600V. It is suitable for underground direct burial and is commonly used for 100-amp service applications in mobile homes and similar installations, with XHHW-2 insulation and a gray PVC jacket for durability.
NASSAU ELECTRICAL SUPPLY 2-2-2-4 SER Aluminum Service Entrance Cable

This 2-2-2-4 aluminum SER cable features four conductors, with an insulated AWG 2/2/2/4 configuration and a bare conductor size of AWG 4. It is designed for standard service entrance use and supports 600V applications with robust amperage capacity for typical residential service runs.
FairySandy 75′ 1-1-1-3 SER Aluminum Service Entrance Cable

Similar to the 50-foot option, this FairySandy 75-foot roll provides 1 AWG conductors in a 1-1-1-3 layout with a 3 AWG bare ground. It is intended for underground direct burial and is rated at 600V, suitable for 100-amp service needs in residential and mobile home contexts.
Relaxweex 2-2-2-4 Feeder Aluminum SER Cable

Relaxweex presents a 2-2-2-4 aluminum SER feeder with 100A capacity and 600V rating, designed for direct burial. The cable is engineered for outdoor environments, offering moisture, corrosion, and sunlight resistance, making it suitable for main feeders to service panels in mobile homes or detached structures.
Buying Guide: How to Choose 100 Amp Aluminum SER Cable
- Conductor configuration: SER cables come in 2-2-2-4 or 1-1-1-3 configurations. The 2-2-2-4 setup is common for 100A main feeders; 1-1-1-3 is typical for certain service entries. Match the conductors to your panel’s lugs and local code requirements.
- Voltage rating and amperage: Look for cables rated at 600V and 100A for residential service feeders. Ensure the rating aligns with the service size and local electrical codes.
- Direct burial vs. above-ground: Direct burial variants are designed for underground runs without conduit, whereas above-ground types may require protective routing. Choose based on installation path and environmental exposure.
- Insulation and jacket: XHHW-2 insulation combined with a robust PVC jacket provides moisture resistance and durability. Verify insulation type matches climate and installation conditions (wet vs. dry locations).
- Length and flexibility: Longer lengths reduce splicing needs but increase cost. Plan lengths to minimize joints and ensure proper bending radii around corners and obstacles.
- Ground conductor: Pay attention to ground wire gauge (often much smaller than phase conductors). Ensure compatibility with the overall grounding scheme and panel requirements.
- Standards and approvals: Confirm compliance with local electrical codes (e.g., NEC in the U.S.) and that the product is listed/approved for service entrance use in the intended setting.
- Installation considerations: Direct burial requires trenching and sealing, while above-ground paths require protective conduit or shielding from physical damage and moisture exposure.
- Cost vs. risk: While aluminum SER is a cost-effective option for long runs, ensure copper alternatives aren’t necessary for certain environments or warranty considerations.
- Safety first: De-energize circuits during installation, use proper PPE, and verify all connections meet torque specifications and require appropriate connectors and terminations.
