I have this up on CL as well and just taking a shot someone might need it, or know someone who does.
From my CL ad:
I have an unused roll of direct burial 4/0 AWG 600V wire. Long story short, my wife and I intended to build a new home a few years ago, bought vacant land, and I started acquiring materials. We re-thought that idea and we bought an existing home instead and sold the land. I now have to use for this.
The label states 500’ on the spool but I think it’s actually around 400’. I lost the original invoice from the supplier in the shuffle of moving but I believe I ordered around 400’. I would be willing to roll this thing out and measure it accurately for a serious interested buyer. I may also consider selling off less than the full roll if the quantity desired makes sense. I’ve listed it below the going rate at $ 2.25/lf and with a cash purchase, there’s no tax. Feel free to contact me with any questions.
I will more than likely unroll this thing over the weekend to establish just how much I actually have, in case anyone wants the whole thing.
