Yeap, special order, and those eaton 50A breakers were half the price as well. I had already stashed a ton of wire that I buy as "leftovers" from my local Lowes. They give away wire remnants at 75% off. One time I picked up about 200ft of white 8awg thhn someone had returned to the store. Got it all for around $12 I think. 6awg not as much, but I'll snag it every time I see it.
