2/0-2/0-1 ALUMINUM SER CABLE

Allowable Ampacity for 2/0-2/0-1 ALUMINUM SER CABLE at 60°C: 115 Amps

Allowable Ampacity for 2/0-2/0-1 ALUMINUM SER CABLE at 75°C: 135 Amps

Allowable Ampacity for 2/0-2/0-1 ALUMINUM SER CABLE at 90°C: 150 Amps

Applications:

Aluminum SER cable is a service entrance cable used in residential and light commercial buildings for panel feeders, subpanels, and branch circuits. It is rated for 600V and is suitable for wet and dry locations with an operating temperature of up to 90°C.

This 2/0-2/0-1 size is commonly used for:

• 150A main service panel feeds in single-family homes (per NEC 310.15(B)(7)).
• Subpanel feeds in larger residential properties, such as multi-unit dwellings or apartments.
• Power distribution from meter bases to 150A panelboards in light commercial buildings.
• Feeding HVAC systems, electric furnaces, and large appliances with high electrical loads.
• Backup generator connections where a 150A-rated feeder is required.

Also Known As:

2/0-2/0-1 type r cable, 2/0-2/0-1 service entrance cable, 2/0-2/0-1 ser cable, 2/0-2/0-1 aluminum ser cable, 2/0-2/0-1 aluminum service entrance cable, 2/0-2/0-1 electrical entrance 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

Construction

Conductors:

The 2/0-2/0-1 designation means this SER cable contains:

• Two 2/0 AWG aluminum phase conductors (hot wires)
• One 2/0 AWG neutral conductor
• One 1 AWG bare aluminum ground conductor
  The conductors are made of compact stranded soft-drawn 8000 series aluminum, cabled together with a reinforced binder tape for structural integrity.

Insulation:

Each conductor is insulated with Type XHHW-2 cross-linked polyethylene (XLPE), providing heat, moisture, and chemical resistance.

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.

• Nominal O.D. Inches: 0.951

• Approx. Weight lb/1000FT: 459 lbs

• Ampacity at 90°C: 150 Amps
