[short]
1-1-1 Bare Concentric Ground Service Entrance Cable (SEU)- CU
Allowable Ampacity at 60° C: 110
Allowable Ampacity at 75° C: 130
Allowable Ampacity at 90° C: 150
Allowable Ampacity (Dwelling): 150
Applications:
SEU is a round and flat electrical cable used in all instances where service entrance cables are allowed. The cable is most often used to connect utility power to the meter base. SEU cable is suitable for wet and dry locations, with temperatures not exceeding 90°C. The voltage rating of the electrical cable is 600 volts.
Also Known As:
Copper SEU Service Entrance Cable, SEU Cable, SEU Service Cable, Copper Service Cable, Unarmored Service Entrance Cable.
Standards:
- ASTM- All applicable standards
- UL Standard 44 for XHHW-2 conductors
- UL Standard 83 for THHN/THWN conductors
- UL Standard 854
- Federal Specification A-A-59544
- National Electrical Code, NFPA 70. 2011 Edition

Construction:
Conductor:
The cable is equipped with annealed soft copper conductors. It typically has two-phase conductors with a concentric neutral.
Insulation:
The cable has cross-linked polyethylene (XLPE) type XHHW-2 insulation.
Jacket:
SE cable is jacketed with gray sunlight-resistant polyvinyl chloride (PVC). This dielectrically strong insulation is resistant to corrosion, abrasion, chemicals, and mechanical impact.

APPLICATIONS
Southwire Type SE, service entrance cable is primarily used to convey power from the service drop to the meter base and from the meter base to the distribution panelboard; however, the cable may be used in all applications where Type SE cable is permitted. SER may be used in wet or dry locations at temperatures not to exceed 90°C. Voltage rating is 600 volts.

CONSTRUCTION
Southwire Type cable is constructed with sunlight resistant Type XHHW-2 conductors or Type THHN/THWN conductors. Copper conductors are annealed (soft) copper. Cable assembly plus reinforcement tape are jacketed with sunlight resistant gray polyvinyl chloride (PVC). Available as 1 conductor with a concentric ground, 2 conductor with a round or concentric ground, or 3 conductor with a bare ground. SE cable is jacketed with gray sunlight resistant polyvinyl chloride (PVC).
