If Virgil's cable is without the outer covering, he is OK all the way. See the little asterisk at the bottom of C10. I'm not sure either.

Also, those tables assume all conductors are the same size. Virgil is using a 2/0 neutral. If you look up the dimensions of RHW-2 in table 5 & add everything up, the area comes to 1.2913 inches & the maximum permitted is 1.316 (table 4) Things get even better if you look up the RHW-2 with the asterisk.


One thing that I do know is that XLPE isn't a listing. It stands for cross linked polyethylene & this is the main ingredient of some of the thermoset insulations.

Few things are harder to put up with than the annoyance of a good example.
