help on URD

[Ingenieur]

if someone could give me a primer

looks like a quad cable
can't find anything in the NEC
how to size conduit if used (I did a 40% calc for 2 awg x 4, diameter = 0.938 and came up with 1.5" pvc)
ampacities per NEC (the mfgs literature has values, direct buried and in duct)

If it's truly URD then it's not listed anywhere in the NEC. Most URD is dual listed USE or RHW so I'd use that chart either way.
