  • Our take on the 250' 2-2-4 ALUMINUM SEU CABLE

    This is service entrance cable with two 2 AWG aluminum conductors and one 4 AWG neutral, rated 600 volts. It is used mainly as a panel feeder in multi-unit dwellings and for branch circuits, and its ampacity depends on the termination temperature: 75 amps at 60°C, 90 amps at 75°C and 100 amps at 90°C. Aluminum SEU is lighter and easier to pull than equivalent copper, but it needs aluminum-rated lugs and terminations and must not exceed 90°C in wet locations. It is the standard choice for residential service and subpanel runs where aluminum feeders are accepted.

    About the 250' 2-2-4 ALUMINUM SEU CABLE

    This is a 250-foot length of 2-2-4 aluminum SEU (service entrance) cable. It has two insulated 2 AWG conductors and a 4 AWG bare conductor. It is rated for 600 volts. It is mainly used as a panel feeder in multiple-unit dwellings and for branch circuits.

    The conductors are compact-strand, soft-drawn 8000 series aluminum, per ASTM B-801. Each has type XHHW-2 cross-linked polyethylene (XLP) insulation. The conductors are cabled together with the bare ground and covered with a reinforced binder tape.

    The jacket is gray, sunlight-resistant PVC. It protects the inner components from outside forces and resists oil, water, flames, acids, chemicals, impact, abrasion and weather changes. Sequential footage markings on the jacket show the length during installation.

    Questions and answers

    What does 2-2-4 mean on this cable?
    It has two 2 AWG conductors and one 4 AWG conductor, the neutral. The two 2 AWG legs carry the hot lines and the 4 AWG serves as the neutral.
    How many amps can it carry?
    Ampacity depends on the termination rating: 75 amps at 60°C, 90 amps at 75°C and 100 amps at 90°C. Size the breaker to the lowest-rated termination in the circuit.
    Can it be used for a subpanel feeder?
    Yes. SEU cable is made for panel feeders in multi-unit dwellings and for branch circuits, up to 600 volts.
    Does it work with standard breakers and lugs?
    Only with aluminum-rated lugs and terminations. Use hardware listed for aluminum conductors and torque connections to the manufacturer's spec.
    Can it be buried or run in wet locations?
    It is rated for wet locations but the conductor temperature must not exceed 90°C there. Check local code for direct-burial rules before installing.
