SER is a flat or round assembly of insulated conductors with an overall jacket, used for service entrance and panel feeders. SEU is the three-conductor version with a bare neutral. Both come in aluminum most of the time and copper when the spec demands it.
Residential electricians buy SER constantly, which means there is always a partial reel on the truck or in the shop.

How SER is identified
- The assembly size printed on the jacket, for example 2-2-2-4
- SER or SEU, since the neutral construction differs
- Aluminum or copper at a cut end
- Feet remaining, or a full reel with the tag
- Whether the jacket is sunlight resistant and still pliable
Assemblies, not single wires
You cannot price SER by adding up four conductor sizes. It is a listed assembly with a specific jacket, and the whole reel is what is bought. That is why the assembly number matters more than the individual gauges.
Wire and cable only
We do not buy transformers, switchgear, circuit breakers, MCCs, generators, bus plugs, chillers, machinery or unrelated scrap. Mixed loads are fine as long as we are quoting the wire portion.
