4-4-4 ALUMINUM SEU CABLE

Allowable Ampacity for 4-4-4 ALUMINUM SEU CABLE at 60°C: 55 Amps

Allowable Ampacity for 4-4-4 ALUMINUM SEU CABLE at 75°C: 65 Amps

Allowable Ampacity for 4-4-4 ALUMINUM SEU CABLE at 90°C: 75 Amps

Applications:

4-4-4 Aluminum SEU cable is primarily used as a service entrance cable in residential applications, supplying 120/240V power from the utility meter to the main breaker panel. It is rated for 600V and designed for dry locations, with an operating temperature up to 90°C.

This 4-4-4 size, with an ampacity of 75 Amps, is commonly used for:

• Main panel feeds in small to medium-sized residential buildings.
• Meter-to-panel connections in homes and duplexes.
• Service upgrades or replacements where a 75 Amp service is required.

Also Known As:

4-4-4 aluminum seu cable, 4-4-4 seu service entrance cable, 4-4-4 seu cable, 4-4-4 seu wire, 4-4-4 600v wire, 4-4-4 600v cable, aluminum cable

Standards:

• Ampacities based on National Electric Code, 2005 edition, section 310-15 

• 60°C when terminated to equipment for circuits rated 100 Amps or less or marked for 14 gauge through 1 gauge conductors 

• 70°C when terminated to equipment for circuits rated over 100 Amps or marked for conductors larger than 1 gauge 

• 90°C wet or dry locations 

• For dwelling units, conductors shall be permitted at listed ampacities to be utilized as 120/240 volt, 3-wire, single-phase service conductors that supply the total load 

• UL 44, 854 

• Federal Specification J-C - 30B

Construction

Conductors:

The "4-4-4" designation means this SEU cable contains three conductors, each with a 4 AWG (American Wire Gauge) size:

• Two phase conductors (hot wires) for carrying current.
• One neutral conductor, which also serves as the ground conductor per SEU cable design.
• The conductors are cabled together with a bare aluminum neutral/ground conductor.
• A reinforced binder tape holds the assembly together.

All conductors are made of compact stranded 8000 series aluminum, providing lightweight properties, corrosion resistance, and electrical conductivity.

Insulation:

Each insulated conductor is coated with XHHW-2 cross-linked polyethylene (XLPE) insulation, which provides:

• High heat resistance (rated up to 90°C).
• Moisture resistance for wet and dry locations.
• Durability against mechanical stress and chemical exposure.

Jacket:

The cable jacket used in its design is Polyvinyl Chloride (PVC). The jacket protects the inner components of the cable from potentially damaging external forces. PVC is robust and resistant to oil, sunlight, water, flames, acids, chemicals, radiation, impact, abrasion, and weather changes. Sequential footage markings that help the user identify the appropriate length during installation are noted on the cable jacket.
