Sell 250 to 500 kcmil (MCM) Wire in Arizona

Which surplus reels belong in this size range

This range covers 250, 300, 350, 400 and 500 kcmil conductors. We buy all types of electrical wire and cable, new, unused, leftover or used. Send photos of full reels, partial reels, boxed coils, cut lengths and mixed lots. Include footage and condition details so we can review your material and make an offer.

Keep different sizes and wire types separate in your inventory. A reel of 500 MCM THHN is not the same product as a reel of 500 kcmil shielded cable. The wire sizes we buy guide covers the broader range. Smaller large-conductor lots belong with 1/0 through 4/0 wire, while larger reels belong with 600 to 1000 kcmil wire.

Size chart and common wire types

The size describes conductor area, not insulation thickness, outside diameter or an automatic current rating. These are typical applications, not instructions for sizing a circuit. Load, conductor metal, installation conditions and termination ratings still matter.

For identification details, compare THHN and THWN-2 building wire, XHHW-2 feeders and USE-2 and RHW-2 wire. These designations identify different insulation systems and permitted uses, even when the conductor size matches.

Read the size from the print line

AWG means American Wire Gauge. Within the numbered AWG sizes, a lower number means a larger conductor. The system also includes 1/0 through 4/0. In kcmil sizes, the number increases with conductor area. One kcmil equals 1,000 circular mils; a circular mil is the area of a circle one thousandth of an inch in diameter. MCM is an older notation for the same unit as kcmil.

A simplified marking example is 350 KCMIL CU THHN/THWN-2 600V. Here, 350 is the conductor size, CU identifies copper, the letters identify the wire type and 600V is the voltage rating. Actual print order varies. An aluminum reel may use AL and carry XHHW-2 markings instead.

Photograph the whole repeated marking, including the manufacturer and date code. Do not confuse a voltage number or sequential footage number with size. Insulation color alone cannot identify conductor size, metal or listing.

Approximate copper and aluminum conductor weights

These estimates describe bare conductor metal only, not finished insulated cable or a loaded reel. Copper is calculated from about 3.03 pounds per 1,000 feet per kcmil, with about a 2 percent allowance for Class B stranding. Aluminum is estimated at about 0.30 times the copper weight. Actual alloy and strand construction can change the result.

Insulation, shields and reel packaging add weight. Do not divide a loaded reel's gross weight by this table to claim remaining footage. Use the wire weight chart to compare other conductor sizes, and use the manufacturer's product sheet when you need finished-cable weight.

Continuous footage matters more than a pile total

There is no universal minimum quantity. For 250 to 500 kcmil wire, send the footage of each continuous piece along with the combined total. We buy both short pieces and uninterrupted feeder runs. Their lengths affect the offer.

Full reels generally have an advantage over short cuts. We also buy partial reels and cut lengths, with footage affecting the offer. List each reel's size, type, metal, color and remaining footage. Mark an uncertain amount as an estimate. Keep original reel footage separate from what remains after pulls.

Matching reels also matter. If your closeout includes several colors or parallel feeder runs, show each length separately. Do not round unequal reels up to a common length. Differences in footage between reels help us review the group and affect the offer.

What affects resale demand and the offer

Size alone does not decide an offer. We review wire type and listing, copper versus aluminum, brand, manufacture date, condition and current demand for that product. More conductor area does not make every 500 MCM length easier to resell than a clearly identified 250 kcmil reel.

Copper THHN/THWN-2 commonly has PVC insulation with a nylon sheath. XHHW-2 uses cross-linked polyethylene insulation, and aluminum products may use compact stranding. Equal kcmil designations do not make copper and aluminum interchangeable for a circuit.

For medium-voltage cable, include voltage class, insulation level, shield details and any available test reports. Protect sealed ends; their condition affects the offer. A size-only description such as 350 MCM leaves out information needed to identify a shielded feeder correctly.

Arizona feeder closeouts and storage condition

Arizona solar and battery projects are relevant places to check for unused feeder inventory. SRP's October 2024 announcement described the Eleven Mile Solar System near Coolidge in Pinal County as a combined solar and battery project. That is project context, not a claim that this project has wire available or sells to us.

If you are closing out a solar or storage job, identify whether each large reel is building wire, underground service wire or shielded medium-voltage cable. The job label alone does not establish the cable's listing.

For reels stored outdoors in Arizona, report sun exposure and water contact. Photograph cracked insulation, crushed cable or broken reel flanges rather than leaving those areas out. These conditions affect the offer. Preserve tags and end seals so the material can be reviewed accurately.

Photos that let us review large-conductor lots

Send a readable reel-tag photo, a close view of the print line and a full-lot photo showing every reel or cut-length group. Include colors, packaging condition and a reel-by-reel footage list. Keep damaged or uncertain items clearly identified.

Use Get an Offer to send those details with the Arizona location. We confirm who is selling and keep simple paperwork, such as an invoice, purchase order, job closeout paperwork or company letter, plus the name of the person releasing the material. We review the lot for a written offer. We pick up anywhere in Arizona.
