NEC Tables for XLPE/PVC power cable sizing?

[nightfox1925]

Hello again gentlemen. I am sizing our low voltage power cables in which we are intending to use 3 core XLPE/PVC power cables. I prefer to use the NEC 2005 since we do not have any information which cable manufacturer we are going to purchase these power cables since this is a proposal project.

Well, in the NEC, for 600VAC 3 core power cables directly buried underground, is it applicable for me to use the NEC table B.310.8 for 8AWG and above and NEC Table 310.16 for sizes below 8AWG?

Where I have single core XLPE/PVC power cables in air, can I use NEC Table B.310.1? I will use 75 Deg table to be conservative since almost all MCCB terminal ratings are rated 75 Deg.

I raise this question since there is no listed XLPE/PVC cable in the tables and I am wondering if this may be applicable. Furthermore, for the resistance and reactance values, I will select a certain cable manufacturer for XLPE/PVC cables since I don't see any table for this in the NEC. The resistance/reactance in the appendices only applies to building wires.

Any NEC expert suggestions?

This has cable ratings for all sorts of cables but note the defined conditions for these ratings and that the sizes are metric
