Our take on the Aluminum Wire SER-2-2-2-2-4-AL-1000R Round Service Entrance Cable

This is 2 AWG aluminum SER round service entrance cable with four conductors, rated 100 amps at 600V and 90°C. It is used for running power from a meter or panel to a subpanel or service equipment, and it is rated for wet and dry locations. It comes on a 1000 ft spool with a gray PVC jacket and XLPE insulation. Shoppers typically compare it by the foot against copper SER and against 2-2-2-4 configurations that add a smaller ground.

Pros
  • Aluminum conductors cost far less than copper at this gauge
  • Four 2 AWG conductors handle a full 100A feeder
  • Rated 600V and 90°C for service entrance use
  • UL 854 listed and RoHS compliant
  • Rated for wet and dry locations
Cons
  • Aluminum needs antioxidant compound and aluminum-rated lugs
  • Bulkier and stiffer to pull than copper
  • Not for direct burial; use USE or UF instead
  • 1000 ft spool is more than most DIY jobs need
  • Requires torque to spec on terminations to avoid loose connections

Questions and answers

Is 2 AWG aluminum SER enough for a 100 amp subpanel?
Yes. Four 2 AWG aluminum conductors are rated around 100 amps in this cable, which matches a 100A subpanel feeder. Confirm the ampacity table and derating for your run length and installation method with your inspector.
Can this cable be buried underground?
No. SER is for wet and dry locations above ground, such as crawlspaces, basements and exterior walls. For direct burial use USE or UF cable instead.
What is the difference between 2-2-2-2 and 2-2-2-4 SER?
Both have three 2 AWG conductors for the two hots and neutral. The 2-2-2-2 has a full-size 2 AWG ground, while 2-2-2-4 uses a smaller 4 AWG ground, which is lighter and cheaper.
Do I need special connectors for aluminum wire?
Yes. Use lugs and connectors listed for aluminum, apply an antioxidant compound, and torque terminals to the manufacturer's spec. Aluminum terminations loosen if not torqued correctly.
How is the 1000 ft spool shipped?
It ships as a single 1000 ft spool, which is heavy and usually needs a freight delivery rather than a parcel carrier. Check the delivery method and liftgate options before ordering.
