im thinking of using some of this wire in a 2'' poly pipe for my 250a 480v 3ph service. im trying to figure out the ampacity using 310.16 and conduit fill for sched 80 pvc using annex c.10. im guessing that id use the 75 degree column inside 310.16 for my ampacity. im going to parralell two 2/0 runs which should be good for 135amps each. i know the wire is installed of 2" poly pipe, but im wondering if i need to go up to 2-1/2 inch for my schedule 80? would it be considered a compact cunductor and which type of wire is it considered?\ i know i wil not be able to land both 2/0 wires in my main breaker so i will set an enclosure and tap 250 kcmil copper off of each 2/0 run.
