XHHW and XHHW-2
XHHW and XHHW-2 appear on feeders, service entrances, rooftop units and industrial power runs, often in sizes from #6 up to 750 MCM.
Wire we buy
We buy surplus THHN, THWN and THWN-2 building wire
THHN and THWN are the most common leftover wire on any commercial or industrial job. If a project ended with partial reels, cancelled orders or unopened cartons, send the tags and a photo of each reel and we will quote the lot.
01Overview
What THHN / THWN surplus usually is
THHN, THWN and THWN-2 are thermoplastic-insulated building wires used for branch circuits and feeders in conduit. Because they are ordered in specific colors and cut lengths, projects routinely finish with a mixed tail of 500-foot and 1,000-foot reels, half-used spools and cartons that were never opened. That tail is exactly what we buy.
Copper is the most common conductor we see, and aluminum THHN and XHHW feeders show up regularly on larger commercial jobs. Both are worth quoting, but they price differently, so the conductor metal has to be clear before we can put a number on the lot.

Send these with the quote request
- Photos of the reel tags, spool labels or printed jacket legend so the wire type can be read exactly.
- One photo of the whole reel, spool or pallet so quantity and packaging are visible.
- Gauge or MCM, conductor metal (copper or aluminum), voltage rating and conductor count where known.
- Approximate footage, reel count or total weight, plus the condition and how it is stored.
- City and ZIP code where the material sits, plus loading access (dock, forklift, ground level).
03Details
How this material is quoted
What makes a THHN lot quotable
The printed legend on the wire jacket tells us the insulation type, size, voltage rating and approval marks in one line — for example a wire printed as THHN/THWN-2, 12 AWG, 600V. A close photo of that print beats any description. If the reel tag is still attached, photograph it too, because tags carry the manufacturer, footage and date code.
Partial reels are fine. We care whether the remaining footage can be estimated from the tag or a counter, and whether the wire has been dragged, kinked or stored outdoors in UV. Wire that has sat in a yard for three summers is a different material from wire that stayed indoors in a warehouse.
Where leftover THHN comes from in Wyoming
Commercial and industrial electrical contractors finishing schools, hospitals, plants and data-center fit-outs; plant maintenance groups replacing feeders during turnarounds; electrical distributors clearing discontinued colors; and agricultural facilities rewiring irrigation and grain systems. We also see full reels from cancelled projects where the material was delivered and never installed.
Sizes, colors and mixed lots
Mixed lots are welcome. A pallet with twelve partial reels in six colors is normal, and it does not need to be sorted before you contact us — but list what you can see. If the lot is large, grouping by size and color in the description speeds the quote up considerably. Very small quantities of common sizes may be worth less than the freight, and we will say so rather than waste your time.
04Questions
THHN / THWN questions sellers ask
Do you buy partial reels of THHN with only a few hundred feet left?
Often, yes, depending on size, color and condition, and usually as part of a larger lot rather than as a single small reel. Send the footage you can read from the tag and a photo of each reel and we will tell you what the lot is worth as a whole.
Does the color matter?
It affects how easily we can place the material. Black, red, blue, white and green move best; odd colors in small quantities are harder. It does not stop us from quoting, it changes the number.
Can you buy wire that has been installed and pulled out?
Sometimes, if it was pulled cleanly and the jacket is intact. Used wire must be clearly described as used or pulled so it is priced as such.
