Specification

250-250-250-3/0 ALUMINUM SER CABLE

Allowable Ampacity (amp rating) for 250-250-250-3/0 ALUMINUM SER CABLE at 60°C: 170 Amps

Allowable Ampacity (amp rating) for 250-250-250-3/0 ALUMINUM SER CABLE at 75°C: 205 Amps

Allowable Ampacity (amp rating)  for 250-250-250-3/0 ALUMINUM SER CABLE at 90°C: 230 Amps

250-250-250-3/0 Aluminum SER Applications:

Aluminum service entrance cable is mainly used in branch circuits and panel feeders. The voltage rating for this electrical cable is 600 volts. Aluminum service entrance cables are designed for use in adverse weather conditions, with operating temperatures being 90°C in both wet and dry locations.

However, type R cables can operate at 60°C when terminated to equipment for circuits rated at 100 Amps or less or if it is marked for 14 gauge through 1 gauge conductors. In addition, SER cables can operate at 70°C when the electrical cable is terminated to equipment in circuits rated over 100 Amps or when marked for conductors larger than 1 gauge.

SER Cable Applications include:

  • Main Feeder Line From a Service Drop To Panel
  • Sub-panel Feeders:
  • Large Appliances like ranges, air conditioning units, furnaces, and other large electrical loads.
  • Workshops and Detached Buildings
  • Agricultural Applications: SER cables can be employed in barns, greenhouses, and other agricultural structures to provide power for equipment, lighting, and other needs.
  •  Multi-Unit Dwellings: In multi-unit residential buildings, SER cable can serve as the main feeder or distribution cable to individual units.
  • Commercial Buildings: In commercial settings, SER cable can be utilized in a similar manner as residential – to serve as feeders to main panels or sub-panels, and to power specific high-load areas or equipment.
  • Service Upgrades: When upgrading the electrical service in a home or building to accommodate more power, SER cable can be a go-to choice for the main feeder replacement.

Particular Applications of 250-250-250-3/0 Aluminum SER are:

  • Residential and commercial service entrance
  • Sub-panel feeders in large buildings
  • Large motorized equipment
  • Multi-unit residential buildings
  • Service Upgrades

  • 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

250-250-250-3/0 Aluminum SER  Construction

Conductors:

Aluminum type R cable has compact strand soft drawn 8000 series aluminum conductor, per ASTM B-801. The conductor is the electrode in the cable and is responsible for transmitting electric current. 

Insulation:

Aluminum SER cable has a type XHHW-2 cross linked polyethylene (XLP) insulation. The conductors are cabled together with a bare aluminum ground and covered with a reinforced binder tape. For color code, see table B in the technical section. 

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.

250-250-250-3/0 Aluminum SER  Specifications:

  • Insulated Cond(s) Size AWG: 250 MCM (3 conductors)
  • Bare Natural Size: 3/0
  • Outside Diameter: 1.601 inches
  • Ampacity: 230 Amps
  • Net Weight: 1.13 lbs/ft
