SELL SURPLUS THHN AND THWN WIRE
The single most common surplus wire in Michigan. If you have a shelf of spools and partial reels from finished jobs, that material has a buyer.
Leftover project wire? Sell it now — don’t scrap it.
Thermoplastic single-conductor wire
THHN is a single copper or aluminum conductor with PVC insulation and a protective nylon jacket, rated 600V. THWN adds a wet-location rating; THWN-2 raises the wet-location temperature rating to 90°C. Nearly all wire sold today carries a combined legend such as THHN or THWN-2.
It is used for branch circuits and feeders in conduit: lighting, receptacles, panels, equipment connections and control circuits. That breadth is exactly why so much of it ends up as surplus.
Sizes, colors and packaging
Common sizes run from #14 through 1000 MCM. The volume sits in #14 to #6 for branch circuits and #4 to 4/0 for feeders.
- Colors — black, red, blue, white, green, brown, orange, yellow, grey and purple; multi-color lots are normal.
- Cartons — 500 ft coils, often unopened, in #14 through #10.
- Spools and reels — 500, 1,000 and 2,500 ft depending on size.
- Partial reels — the standard contractor leftover, often with footage written on the flange in marker.
Where surplus THHN comes from
Four situations account for most of the THHN we are offered:
- Job overage — wire ordered with contingency that was never installed, still banded and tagged.
- Design changes — a circuit resized or rerouted after the wire was purchased.
- Partial pulls — a reel opened for one run and left with most of its length.
- Obsolete stock — colors and sizes a shop no longer keeps on the truck.
We buy all four, and we quote them differently: sealed factory cartons, tagged full reels and open partials are three different products.
What reduces the value
- Sun-faded or cracked insulation from outdoor storage
- Reels stored on the ground, with the bottom wrap sitting in water
- Missing tags where the print legend has also worn off
- Crushed or broken reels that require re-reeling
- Wire contaminated with concrete dust, oil or paint
A photo of the reel tag and one of the wire itself usually settles all of it. Where the tag is gone, photograph the printing on the jacket close enough that the text is readable.

Questions sellers ask before they call
Do you buy partial spools of THHN?
Yes. Partial spools and reels are the most common surplus we buy. Tell us the approximate remaining footage and the size.
Do you buy mixed colors?
Yes. Mixed lots are normal; describe the sizes and quantities by color if you can, or photograph the shelf.
Do you buy THHN that was stored outdoors?
It depends on the condition of the insulation. Photograph the jacket closely — UV damage is visible as fading and fine cracking.
Do you buy #14 and #12?
Yes, in cartons and partial spools. These sizes are usually quoted as a lot rather than individually.
