Had a project last quarter where teh 3-conductor layout saved us an entire re-pull because someone misread the print, and after that we basically decided to stick with the color-coded setup.
It's stranded copper, THHN-rated PVC insulation with a 90°C rating, and the bare ground gets its own kraft paper wrap so it doesn't chafe against live conductors during insallation.

UL719 certified, so you're covered for residential rough-in without having to explain anything to the inspector.

The 2-conductor comes white and black, the 3 adds red, and you can get it in 250ft or 500ft reels — most buyers go with the 500 for standerd floors.

We usually have stock on the 250ft and 500ft, but the 1000ft spools are special order and lead time is about 10-15 days or so depending on their schedule.
Not great for outdoor direct bury obviously, and don't try it in conduit fills above 40% — the flat profile jams up pretty quick.
We offer 2-conductor (white/black) and 3-conductor (white/black/red) versions. Both include a bare copper ground wire with kraft paper wrapping, as per the UL719 standard.
Our MOQ is typically one full spool, which comes in either 250ft or 500ft lengths. We don't cut partial spools, so you'll need to pick one of those two sizes.
Yes, we include the UL719 certification paperwork with every order. We can also supply the ASTM B3 compliance docs for the stranded copper conductor if you need them.
Lead time is usually 7-10 business days from order confirmation for stock sizes (250ft or 500ft spools). Custom lengths or special packaging might add a few days, but we'll confirm that upfront.
Each spool is wrapped in kraft paper and then shrink-wrapped for moisture protection. The paper wrap is just a separator for the bare ground wire—it won't affect the cable's shelf life if stored in a dry area. We recommend keeping it indoors.
