Ohio Wire Buyers buys reusable surplus SER and SEU service entrance cable from businesses anywhere in Ohio, as product for resale and reuse rather than scrap metal by the pound. To sell SER cable or SEU leftovers, send photos of the jacket markings, existing cut ends and reels or coils, plus a footage list or estimate. We review the material for a written offer before arranging pickup.
What separates SER from SEU cable?
SER and SEU belong to the Type SE service entrance cable family, but their conductor arrangements are not interchangeable. In the familiar four-wire SER assembly, the insulated phase conductors and insulated neutral run with a separate bare grounding conductor. Southwire's aluminum SEU construction instead uses insulated phase conductors with bare aluminum neutral wires applied helically around them.
| Identification point | SER, Style R | SEU, Style U |
|---|---|---|
| Neutral arrangement | Insulated neutral in the assembly | Bare neutral; Southwire aluminum versions use helically applied wires |
| Separate ground | Included in the SER configurations discussed here | Not a separate fourth conductor in the typical service assembly |
| Useful photo | End showing insulated conductors and bare ground | End showing insulated conductors and bare neutral arrangement |
| Outer jacket | Gray, sunlight-resistant PVC in the cited Southwire products | Gray, sunlight-resistant PVC in the cited Southwire products |
Construction can vary by product and size. Encore's copper SEU sheet, for example, describes a parallel bare conductor in smaller sizes and helically wrapped bare wires in larger sizes. Read the markings and inspect the existing end instead of identifying the cable by shape alone. Our wire and cable categories help separate SE assemblies from other surplus.
How do you read a SER size string?
A label such as 2-2-2-4 identifies conductor sizes, not footage. For the SER configuration below, the first three entries describe the insulated conductors, including the neutral; the final entry describes the bare ground. Record every entry rather than shortening the description to “number two aluminum.”
These aluminum configurations appear in Southwire's SER specification.
| Aluminum SER size string | Insulated conductors | Bare grounding conductor |
|---|---|---|
| 2-2-2-4 | Three 2 AWG conductors | 4 AWG |
| 1/0-1/0-1/0-2 | Three 1/0 AWG conductors | 2 AWG |
| 2/0-2/0-2/0-1 | Three 2/0 AWG conductors | 1 AWG |
| 4/0-4/0-4/0-2/0 | Three 4/0 AWG conductors | 2/0 AWG |
These are identification examples, not service-sizing recommendations. Copper versions also exist, and a copper size is not interchangeable with the same aluminum size. Send the complete manufacturer's designation when a reel has a different conductor count or reduced neutral.

Which ratings matter when identifying reusable cable?
Southwire lists its cited SER and SEU products under UL 854 for service entrance cable, with a 600-volt rating. Its aluminum versions use AA-8000-series building wire conductors. The SER specification describes individual conductor insulation as XHHW-2 or THHN/THWN; the actual jacket legend tells us which version the seller has.
Photograph those letters rather than assuming every service cable has the same insulation. Separate XHHW-2 building wire is a different inventory item from an intact SER assembly containing XHHW-2 conductors.
A conductor's insulation designation does not expand the permitted uses of the finished cable. Southwire's SEU specification explicitly excludes underground installation, with or without a raceway. Do not combine SE cable with underground distribution surplus under one description. A qualified electrician must determine installation suitability and actual allowable loading.
Selling leftovers from apartment feeders and service work
For an Ohio contractor closing out an apartment or multifamily job, describe leftover feeder cable by its product markings, not by the apartment number it was intended to serve. Encore identifies SER as a feeder from the main distribution panel to remote panels. Whether a particular leftover can serve another installation depends on its configuration, length, condition and that installation's requirements.
Unpulled cable remaining on a reel and separately cut feeder lengths should be listed separately. Distinguish unused cuts from cable removed during a change order or renovation. Include that history with your contractor surplus wire inquiry.
Do not add disconnected pieces together and describe them as one usable run. A future installation needs a suitable continuous length. If footage is uncertain, follow our guide to measuring cable left on a reel and identify estimates as estimates.
What condition problems should you disclose?
Keep the gray outer jacket intact. Flag crushed areas, deep cuts, sharp kinks, exposed insulated conductors and damage near the ends. For SEU, also photograph displaced or severed bare neutral wires. An assembly with missing strands is not equivalent to a complete factory product.
Tell us how the material was stored and whether it was ever installed. Do not describe used cable as new because it looks clean. If lugs remain attached, photograph them and explain the removal history instead of cutting back every piece before review.
Leave coils secured without forcing tight bends, and retain sound reels and readable labels. Surface dirt and uncertain history are different issues; cleaning the outside does not establish electrical condition. Used material is considered only when still reusable, and photos alone are not an electrical certification.
What should you send for a service entrance cable offer?
Photograph the whole lot first so we can distinguish reels, coils and loose cuts. Then assign each item an identifier that matches its footage-list entry. This avoids confusing similar gray-jacketed products when reviewing a mixed lot.
Send the following details for each item:
- A readable jacket legend showing manufacturer, Type SE style, conductor material, sizes and insulation designation.
- The reel tag or coil label, including any part number and original footage information.
- Existing cut-end photos showing the insulated neutral or bare neutral arrangement and any separate ground.
- Remaining continuous footage, with the measurement method or basis for the estimate.
- Condition notes, installation history, damage photos and the quantity of separate pieces.
Our reel-tag reading guide explains how to distinguish original put-up information from remaining footage. Do not unwrap an entire reel or cut a fresh sample just to obtain a picture. Only photograph ends that are safely accessible; never cut or handle energized cable for an offer.
Why is the offer about usable product, not pounds?
The complete assembly is what we evaluate for resale. Conductor material matters, but so do the exact size combination, continuous footage, legible identification, condition and demand. A heavier mixed pile does not necessarily have more reusable product than a smaller, clearly documented lot.
Preserving the neutral, ground, insulation and outer jacket keeps the product identifiable. Stripping the cable changes the sale into a metal-recycling question. Our surplus value versus scrap price guide explains that distinction. If the material is not reusable, we say so; a scrap metal recycler may be the right buyer.
Where can you sell SER cable in Ohio?
Ohio Wire Buyers arranges pickup at the seller's jobsite, warehouse, plant or yard anywhere in Ohio. We have no Ohio street address, office or yard, and do not accept seller deliveries. Tell us where the lot sits and whether pickup involves a loading dock, forklift, restricted access or coils that need to be gathered together.
We review your information and reply with questions or a written offer before pickup. Payment method and timing are confirmed in writing before pickup, and the count is checked against the written terms. The selling process also includes seller and ownership verification, with a written purchase record.
Provide an invoice, purchase order, closeout paperwork or company letter as ownership documentation. Keep rented or returnable packaging obligations separate from the cable you own.
Ready to clear identifiable, reusable service entrance surplus? Request an offer for your SER or SEU lot with jacket photos and continuous lengths, or call 951-403-5738 to discuss what information to send.
Frequently asked questions
Does the U in SEU mean underground cable?
No. SEU identifies Type SE, Style U; it is not an underground-use designation. Southwire states that Type SE cable is not permitted underground, even inside a raceway. Do not describe a surplus reel as direct-burial cable based on its name, gray jacket or the insulation rating of the individual conductors.
Do you buy copper service entrance cable as well as aluminum?
Yes. Ohio Wire Buyers buys reusable surplus copper and aluminum service entrance cable from businesses. Identify the conductor material from the jacket print, reel label and existing cut ends rather than assuming every gray cable is aluminum. Keep copper and aluminum items on separate lines in your footage list so the offer describes the correct product.
Can I sell SER cable without its original reel label?
A missing reel label does not automatically rule out reusable cable, but other identification must be clear. Send readable jacket-print photos, existing end photos and a footage estimate with its basis. Tell us that the tag is missing. We may ask for additional information before deciding whether we can make a written offer.
Should I remove the bare conductor before selling SEU?
No. Leave the cable assembly intact. The bare conductor is part of the manufactured product, not loose scrap to remove for a separate sale. Cutting it away changes what remains and can eliminate the assembly's usefulness. Photograph the existing end and jacket instead; never open or cut energized cable to prepare an offer request.
Can removed service entrance cable be considered for reuse?
Used cable is considered only if it is still reusable. Send its removal history, markings, continuous lengths and clear photos of any damage or attached lugs. Removal must be handled by qualified people after de-energization. We do not assume a cable is reusable merely because it carried power before removal; condition and identification still matter.
