Description

GEARit 12 gauge THHN wire is single-conductor copper building wire for conduit, raceway, branch circuit wiring, feeders, panels and general electrical installations. Choose solid or stranded copper, your color for easy circuit identification, and a 50, 100, 150 or 200 ft spool.

Features
  • THHN building wire: Single conductor 12 AWG copper wire for approved conduit and raceway systems, branch circuits, feeders and panels.
  • Solid or stranded copper: Solid copper gives firm terminations on fixed runs, junction boxes and panels; stranded copper is easier to pull through conduit with bends.
  • 600V, 90°C rated: PVC insulation with a tough nylon outer jacket helps resist heat, moisture, oil, gasoline and abrasion.
  • Built for the job: General-purpose 12 AWG for branch circuits, outlets, garages, workshops, panels and residential or commercial conduit runs.
  • Color-coded jackets: Black, red, white, green and yellow help identify hot, neutral and ground conductors during installation.

bigger reel makes it easier to pull

I needed (2) 50' rolls of red THHN. Box store close to me was out. Found this online. Very fast delivery and saved me from having to go to more than one store. These were on a bigger reel than the store and much easier to pull.

Good wire, fast shipping!

Hard to find this in local diy mega stores and if they have some in stock they are proud of it. I never found the three colors I needed at any one location so getting this in two days with prime shipping was excellent.It’s good wire, was easy to pull as needed.

Looks like good quality wire, beware of quantity

The wire looks good and it's as described. Unfortunately, I ordered 100ft and I received about 82ft. Luckily the longest run for my project was 71ft, so I had about 11ft remaining. Needed to use other wire to finish it.

Good quality wire!

I purchased this wire for a sub panel installation and it was of great quality. It was not too stiff and was easy to pull and looks great. The price was good and I would definitely recommend it.

NOT DUAL RATED FOR DRY OR WET LOCATIONS

Although the picture in the listing shows THHN/THWN-2, the wire I received only states THHN, DRY. I didn't get to my project until after the close of the return window, so I'm stuck with it.It is often the case that, on the outside of the wire roll packaging for this type of wire (for example, what you would get at big box stores), it is stated that it is "THHN," but the actual product is dual-rated, and I thought this would be the case with this product, especially after viewing the image. Not so. Do not be fooled if you need this for a wet location. It may be fine for dry locations, but for home use, I really don't need this wire where I can just run Romex. For the three jacket colors I bought, I'm just out the $100.
