We ordered 500 feet of 4 AWG and a 250-foot spool of 250kcmil, dilevery in about 2-3 weeks—lead time varies depending on the gauge you pick, but 14 AWG usually ships faster since they keep more stock.

The XLPE insulation is what makes this work for both dry and wet locations, and with XHHW-2 rating you get 90°C wet/dry which is basically the same spec as the standdard XHHW but without teh derating headache when moisture is a factor, so it's pretty much the go-to for industiral wiring in conduit runs.

Also, the stranded conductor is easier to pull through tight bends than solid core—most buyers go with copper for the lower resisance, but the aluminum alloy option is lighter and cheaper if your run is long and you're not pushing full ampacity, though you'll need anti-oxidant compound on the terminations.

It's UL certified and meets ASTM B3, B8, and B-800, which is tighter tolerance than some generic import stuff we've seen, but for 600V AC circuits in dry locations you could get away with a less expensive cable—just don't expect the same wet-rating or the 90°C temp margin if you ever need it.

One thing we usually have stock on is the 10 AWG and 12 AWG sizes, but confirm lead time on anything above 350kcmil—those are special order and take 20 days or so (check the COA for that batch, as the compact stranding can vary slightly by mill run).
XHHW is rated 75°C in wet locations and 90°C dry, while XHHW-2 is rated 90°C for both wet and dry. If you're running in a wet environment and need the higher temp rating, go with XHHW-2.
It's UL Certified and complies with ASTM B3, B8, B-800, B-801, and B-836. We can provide a certificate of compliance with your order.
Yes, we offer both copper and aluminum alloy conductors. Just specify which you need when placing your order, and we'll match it to the available sizes from 14AWG to 500kcmil.
MOQ depends on the size and conductor material, but for standard sizes like 14AWG to 500kcmil, we usually require 500 feet minimum. Lead time is typically 2-3 weeks for standard orders.
Keep it in a dry, cool area away from direct sunlight and chemicals. Since the XLPE insulation handles moisture well, just avoid long-term exposure to standing water or extreme heat.
