How are you using conductor insulation XLPE? my boss ordered triplex XL # 2 AWG aluminum to be used as an underground feeder from service to a sub panel to a building.

Everybody commented on my last post that this could not be used because it was not listed in NEC table for conductors or cables?

O wow that’s near India region I believe and now makes sense but what place or usage does this cable have in America then? Or why would it be sold here?

There are plenty of things that use electricity and wires that are not governed by the NEC. The whole North American power grid for one. Inside a mine or gravel pit is another.
