Conductor Insulation Voltage Ratings

[stevee]

Where in the NEC can I find the voltage ratings of different types of conductor insulations?

There is some information in Tables 310.13(A) through Table 310.13(E), but the information you seek is found from cable manufacturer literature.

What you want will come from the cable manufacturer. It sounds like you are expecting that each type of insulation has one, and only one, voltage rating. That isn't the case, necessarily.
