THHN and THWN wire buyers in Louisiana
THHN and THWN are the most common conductors in any Louisiana plant storehouse — and the most often sold by weight when nobody reads the tag.
Start here 01
Sell thhn / thwn wire in Louisiana
THHN, THWN and THWN-2 are 600 V thermoplastic-insulated, nylon-jacketed conductors used in conduit and raceway. The letters carry the rating: THHN is rated for 90°C in dry locations, THWN for 75°C in wet locations, and THWN-2 for 90°C dry or wet. Most modern stock is dual- or triple-rated and printed that way on the jacket.
- Construction, size and footage, not weight alone
- Reel tags and jacket print travel with the lot
- Pickup planned around your site, not ours

What this family covers 02
THHN and THWN wire we review in Louisiana
That print is the value. A reel of 4/0 copper THHN with a legible legend and a starting footage is still usable conductor for a contractor or a plant storeroom. The same reel with the tag gone and the jacket sun-cracked is a recovery item. The review separates the two before any number is discussed.
Identification 03
What identifies thhn / thwn wire
The facts that decide how a lot is read. Send what the reel says rather than a description from memory.
| Voltage rating | 600 V, 60 Hz, in conduit or raceway |
|---|---|
| Insulation | Thermoplastic PVC with a nylon jacket; THWN and THWN-2 add a wet-location rating |
| Temperature | 90°C dry for THHN and THWN-2; 75°C wet for THWN; 90°C wet for THWN-2 |
| Sizes we see | 14 AWG through 1000 kcmil, solid in small sizes and stranded above 10 AWG |
| Conductor metal | Copper is the norm; aluminium appears in larger feeders and service work |
| What identifies it | Surface print, reel tag, conductor stranding, jacket colour and the footage stencil |
If a detail is unknown, mark it unknown. A stated uncertainty is workable. A guess that turns out wrong costs everybody a second visit.
Constructions 04
THHN and THWN wire lots we buy
Read separately, because they are valued separately.
Dual-rated THHN/THWN-2
The standard plant and contractor conductor. Reviewed on conductor size, footage and jacket condition, not on weight alone.
Large feeder sizes
500 kcmil through 1000 kcmil copper pulled on industrial feeders. Reel diameter and remaining footage decide how the lot is read.
Aluminium THHN
Aluminium and compact aluminium conductors from service and feeder work, valued against aluminium rather than copper content.
Part reels and cut lengths
Coils and partial reels from maintenance work. Reviewed honestly when the remaining length is measured rather than guessed.
How a lot is read 05
How thhn / thwn wire is evaluated
The first question is footage, and the second is whether the footage is documented. A reel tag with a starting length and a visible remaining wrap is evidence. A coil on the floor with a hand-written note is a claim, and it is read as one.
After footage, the review looks at the jacket — sun exposure, abrasion, oil staining and water ingress at the reel core — then at the conductor size and stranding, the manufacturer, and whether the material was stored indoors or in an open Louisiana yard.
Safety first. Do not cut, strip or pull conductor that may still be connected. De-energising, lockout and proving dead belong to qualified plant personnel under the site electrical safety programme.

Questions —
THHN / THWN wire questions
Do you buy partial reels of THHN?
Yes, when the remaining length can be established. A partial reel with a readable tag and footage stencil is reviewed as usable conductor. A partial reel with no identification is normally read as recovery material and valued accordingly.
Is THWN worth less than THHN?
Not on its own. The wet-location rating usually helps a lot, because dual- and triple-rated print is accepted in more locations. Condition and documented footage matter far more than the letter sequence.
How is aluminium THHN handled?
It is reviewed as aluminium conductor, priced against aluminium content and the construction rather than copper. Larger aluminium feeders are still worth a proper look when the footage is documented.
What if the jacket print has faded?
Say so and photograph what remains. A reel tag, a purchase record or a manufacturer label on the flange can carry the identification. If nothing survives, the lot is reviewed as mixed conductor rather than as a known construction.
