Sell Bare Copper and Insulated Ground Wire in California

California Wire Buyers purchases unused grounding stock and scrap copper throughout California. You can sell bare copper wire as full reels, partial reels, labeled coils, or material removed from service. We also evaluate tinned copper and insulated green grounding wire, keeping each construction separate.

Sell bare copper wire as a product, not just a weight

An unused coil of 6 AWG solid soft-drawn copper is identifiable electrical inventory. So is a tagged reel of 2/0 stranded grounding conductor. Neither has to be treated as mixed scrap simply because there is no insulation.

The important questions are size, solid or stranded construction, temper, coating, continuous length, and condition. Those facts establish what the material actually is. For other constructions in the same yard, our wire-type catalog separates grounding stock from insulated power and specialty cable.

Bare copper has no standalone insulation voltage rating. Do not describe an uninsulated grounding reel as 600V cable just because it was stored beside building wire. Its use and suitability require a separate review by the buyer and end user.

Solid, stranded, soft-drawn, and tinned stock

Soft-drawn, also called annealed, describes copper's temper. It is easier to form than hard-drawn material. Solid and stranded conductors can both be soft-drawn, so those words answer different identification questions.

Grounding inventory often includes 8, 6, 4, and 2 AWG, along with 1/0 through 4/0. A manufacturer's broader bare-copper family may extend from 14 AWG to 1000 kcmil (MCM), but that does not establish every size in every temper or package.

Southwire's bare copper specification distinguishes hard, medium-hard, and soft tempers. It also identifies overhead transmission and distribution applications separately from more flexible construction grounds and jumpers. We retain those distinctions when evaluating a lot.

Tinned copper has a tin coating over copper; it is not aluminum merely because its surface looks silver. Record the manufacturer's coating description rather than guessing from color. For reusable stock, the specified coating is part of the product, not simply contamination to be removed.

Green insulation does not identify the whole ground wire

Ground wire describes a function. Green THHN/THWN-2, green XHHW-2, bare copper, and specialty bonding products are different inventories. Factory green/yellow identification should also be recorded separately from field-applied tape or stripes.

Read the jacket for type, AWG or kcmil, conductor metal, voltage, temperature, and manufacturer. A green color does not establish size or a lower insulation rating. For example, green wire marked THHN/THWN-2 keeps the ratings associated with that actual product.

Small insulated grounding stock may arrive on 500-foot spools, while larger wire comes on 1000-foot or bulk reels. Bare copper also appears in 25-, 50-, 100-, or 250-foot coils and 500- or 1000-foot packages. These are common put-ups, not a rule linking one gauge to one length.

Confirm copper through the conductor, not its surface

Copper-clad steel and copper-clad aluminum are not copper throughout. A copper-colored exterior therefore does not establish solid-copper composition. Here, 'solid copper' concerns metal composition; a stranded conductor can still be copper throughout.

Look for CCS or CCA identification on labels, invoices, and product records. Photograph an already exposed end if available, without cutting an otherwise useful reel merely for an initial inquiry. The underlying core can differ from the copper-colored surface.

Copper-clad steel is a real grounding construction, not necessarily a mislabeled product. Copperweld describes its CCS construction as copper bonded to a steel core. Its metal recovery cannot be assessed as the same weight of copper throughout.

California grounding surplus and ownership records

Grounding grids at solar farms, substations, and data centers can produce surplus after design changes or completed runs. Solar project leftover wire may include bare ground reels alongside PV conductors. Keep those categories on separate inventory lines.

Large data-center cable lots can likewise contain stranded grounding conductors, insulated grounds, and feeder remnants. Original purchase records help distinguish unused project stock from recovered wire. Indicate who owns the material if a contractor is clearing an owner's laydown area.

Grounding conductors at utility and telecom sites deserve careful provenance checks because these sites are vulnerable to theft. We need lawful ownership and disposition documentation, not just an explanation of where the wire was found. Covered agency material requires the appropriate agency-letterhead certification; ordinary project paperwork is not automatically a substitute.

Our California copper-selling rules guide explains the broader requirements. This page gives a summary, not legal advice. We confirm the applicable records and payment terms before pickup rather than treating bare wire as an exception.

When grounding stock belongs in the scrap category

Previously buried pieces, short cutoffs, damaged wire, and material with uncertain specifications need a different evaluation from labeled unused reels. Copper content matters, but condition and contamination also matter. Gross reel weight still includes the packaging.

Keep bright uncoated wire apart from tinned, soldered, coated, or contaminated copper. Bare bright, No. 1 copper, and No. 2 copper are scrap buying categories, not interchangeable names for every bare conductor. Our copper wire grading guide covers the sorting distinctions without turning a photograph into a guaranteed grade.

We also buy scrap copper wire, including used and stripped material. For covered nonferrous purchases, seller identification, material records, photographs, and thumbprints are required as applicable. California payment-timing rules and their exceptions are transaction-specific; payment method and timing are confirmed in writing.

What to send for a bare-copper or ground-wire offer

A useful submission separates each gauge and construction:

• Coil labels or reel tags identifying manufacturer, nominal size, and original footage.
• Close-up photos showing solid or stranded construction, plus stated strand count if available.
• The marked temper: soft-drawn, annealed, medium-hard, or hard-drawn.
• Bare, tinned, CCS, or CCA identification supported by product records and exposed-end photos.
• Full jacket print for insulated green or green/yellow wire, including voltage and temperature.
• Length per continuous piece or coil, with rewound packages and uncertain estimates clearly noted.
• Photos of oxidation, soil, solder, coatings, broken strands, or other visible condition differences.
• Purchase or disposition records, California city, package count, and loading details for heavy reels.

Keep the labels with their matching coils, and do not combine different tempers or gauges into one unidentified bundle. We can pick up anywhere in California. Our written offer will distinguish reusable grounding stock from copper evaluated for scrap.
