Ohio Wire Buyers buys reusable surplus 600, 750 and 1000 MCM copper and aluminum wire from businesses anywhere in Ohio, including full reels, partial reels and usable cut lengths. To sell 750 MCM wire or another large feeder size, send identification photos and remaining footage for a written offer before pickup; we buy cable for resale and reuse, not as scrap by the pound.
How do you sell 750 MCM wire without losing its identity?
Keep the reel tag, printed wire legend and remaining length together. A description such as “large black feeder” leaves important questions unanswered: conductor metal, insulation type, voltage rating and whether the footage is continuous. MCM and kcmil describe the same nominal conductor size, but neither describes the complete cable.
Start your inventory with the size exactly as marked. Then record copper or aluminum and the full insulation designation. Our overview of wire sizes we buy covers the size groups; this page focuses on the additional identification and handling work that large feeders require.
Do not strip the insulation or divide a long run into short pieces before review. That removes product information and changes the usable lengths available to the next buyer.
What are the copper and aluminum ampacities?
The following values are from NEC Table 310.16, 2023 edition, as reproduced in HELUKABEL's published ampacity reference. Values are amperes for not more than three current-carrying conductors in raceway, cable or earth, at an ambient temperature of 30°C.
| Size, kcmil/MCM | Copper 60°C | Copper 75°C | Copper 90°C | Aluminum 60°C | Aluminum 75°C | Aluminum 90°C |
|---|---|---|---|---|---|---|
| 600 | 350 | 420 | 475 | 285 | 340 | 385 |
| 750 | 400 | 475 | 535 | 320 | 385 | 435 |
| 1000 | 455 | 545 | 615 | 375 | 445 | 500 |
Terminations and conditions of use govern the actual rating. A 90°C insulation marking does not automatically allow use of the 90°C column at the terminals. Ambient-temperature correction, conductor-count adjustment and other applicable requirements must be evaluated for the installation.
These are not medium-voltage cable ratings. The table is a reference for identifying building-wire capabilities, not approval for a proposed feeder or permission to substitute aluminum for copper.

How heavy are these conductors, and what reel lengths are listed?
Southwire's SPEC10000 distinguishes copper metal weight from total insulated-wire weight. Both columns below are approximate pounds per 1,000 feet for that manufacturer's copper THHN/THWN-2 construction; neither includes the reel. Packaging examples come from Encore's copper THHN product sheet, not a universal shipping standard.
| Size | Approx. copper-only weight, lb/1,000 ft | Approx. insulated-wire weight, lb/1,000 ft | Encore listed THHN reel lengths | Application examples; design governs |
|---|---|---|---|---|
| 600 kcmil | 1,852 | 1,992 | 500, 1,000, 2,000, 3,000 ft | Commercial and industrial services or feeders |
| 750 kcmil | 2,315 | 2,470 | 500, 1,000, 1,500, 2,500 ft | Large building services or feeders |
| 1000 kcmil | 3,087 | 3,264 | 500, 1,000 ft | Large feeders; separate MV products also exist |
For loading, use gross reel weight, including the reel and packaging. A copper-only figure leaves out insulation; even the insulated-wire figure leaves out the wooden or steel reel. Compare your actual tag and product specification rather than applying these THHN weights to shielded power cable.
Which wire types come in these large sizes?
Southwire lists all these sizes in copper THHN/THWN-2 building wire. Its construction uses PVC insulation and a nylon sheath, with a 600 V rating. Preserve both THHN and THWN-2 markings when recording dual-rated stock.
The manufacturer's aluminum XHHW-2 feeder wire also includes these sizes. That product uses cross-linked polyethylene insulation and an aluminum-alloy conductor. A 750 MCM aluminum reel should therefore be listed by its complete product description, not treated as interchangeable with a same-size copper reel.
For primary underground distribution cable, Southwire's 1000 kcmil aluminum EPR example is rated 15 kV and includes copper concentric neutrals. Those copper wires surround an aluminum phase conductor; their presence does not make the main conductor copper. Submit medium-voltage cable separately with its voltage class, insulation information and neutral or shield construction.
What makes a partial reel useful for resale?
Continuous footage matters more than a combined total spread across disconnected pieces. Keep each length identifiable, especially when a feeder set has several matching reels. Record the length available on each reel instead of assuming the set is equal because the original order was equal.
Encore's cited THHN sheet lists sequential footage markings on these large sizes. Photograph accessible marks and explain whether the recorded length comes from those marks, documented cuts or an estimate. Our guide to measuring wire left on a reel explains how to report uncertainty without unwinding the entire reel.
Separate unused leftovers from previously installed cable, and show abrasions, flattened sections, damaged ends or splices. If the lot also contains 500 MCM feeder wire, keep its footage on separate lines. Reusable product identity, length, condition and demand affect the offer; size alone does not establish a price.
What should you send for a large-feeder offer?
Use a reel-by-reel list rather than one total weight. Include the business selling the material and its Ohio pickup location, along with the following details.
| Information to send | Detail specific to large feeders |
|---|---|
| Whole-lot and reel photos | Show flanges, packaging, accessible tags and how the reels are stored |
| Complete printed legend | Capture size, manufacturer, copper/aluminum, insulation type and voltage marking |
| Cut-end photos | Show conductor metal and any shield or concentric neutral without making a fresh cut |
| Remaining footage | Identify each continuous length and label measured versus estimated quantities |
| Condition and history | State unused or previously installed; show damage, splices and existing lugs |
| Loading information | Provide gross weights if known, reel dimensions and available handling equipment |
The wire-offer photo guide can help organize readable close-ups. Include an invoice, purchase order, closeout paperwork or company letter showing ownership. Ohio Wire Buyers verifies the seller and proof of ownership and keeps a written purchase record.
How should heavy reels be stored and moved?
Check reel condition before planning a lift. Southwire's handling guidance calls for reel flanges to remain vertical, with the reel supported on a firm, level surface. It directs forklift operators to support both flanges without contacting the cable; crane handling uses a shaft through both arbor holes and an appropriate spreader.
Use qualified operators and equipment rated for the actual load. Send reel dimensions and weight information before pickup so the handling plan does not rely on a guessed cable weight. Tell us if a forklift or crane is unavailable.
Southwire recommends indoor storage for building wire and sealed ends on insulated cable. Keep existing end protection intact, secure loose ends, and disclose missing caps or water exposure. Do not move a damaged reel merely to get a better photograph.
What happens after the lot is reviewed?
Ohio Wire Buyers reviews your photos and footage list, then replies with questions or a written offer before pickup. Payment method and timing are confirmed in writing before pickup. We arrange pickup at your Ohio jobsite, warehouse, plant or yard and check the count against the written terms; the selling process explains these steps.
If the cable is not reusable, we say so; a scrap metal recycler may be the right buyer. To submit large feeder reels or cut lengths for review, get an offer or call 951-403-5738 with the size, insulation type and available footage.
Frequently asked questions
Does 750 MCM mean the same size as 750 kcmil?
Yes. MCM and kcmil are alternative designations for the same conductor-area unit, so 750 MCM and 750 kcmil identify the same nominal size. That does not identify the complete product. Copper or aluminum, insulation type, voltage rating, stranding and usable length still need to be recorded from the wire markings and reel tag.
Can I sell aluminum feeders together with copper wire?
Yes, you can submit a mixed surplus lot for review. List aluminum and copper separately even when both carry the same size marking. Include each reel's insulation type, color, footage and condition. Ohio Wire Buyers evaluates reusable material as wire or cable product, rather than applying a single scrap-metal price to the entire lot.
Does a 600 marking on the jacket always mean 600 MCM?
No. A marking of 600 V describes voltage rating, not conductor size. A size marking should identify kcmil or another size designation. Send a readable photograph of the complete printed legend rather than a close-up of one number. For example, a large THHN conductor can have separate size and voltage markings on the same jacket.
Are feeder lengths with installed lugs worth submitting?
They can be worth submitting if the cable remains reusable. Photograph the lugs, exposed conductor, insulation transitions and complete length, and explain whether it was installed or unused. Do not remove terminations or cut off sections just to prepare photos. Installed cable must be safely de-energized and removed by qualified people before it is handled for sale.
Will a reel tag prove how much wire remains?
A factory tag can identify the original shipment, but it does not establish remaining footage after cable has been pulled. Send the tag with a separate remaining-length estimate and explain its basis. Visible footage markings, documented cuts or a material-specific weight estimate can help. Label uncertain lengths as estimates instead of representing them as measured footage.
