Table 310-77 Hight Voltage cable 2001-5000v
90c MV 90 and 105C Mv 105 Wire size as an Example #1 = 90c(MV90)=170amps
#1 = 105c(MV105)=180 amps
Terminations 110.40
States terms to be rated at 90c unless otherwise idenitfied.
Question is Wire rated at 90c for terms 105 for derateing.
Simlar to under 600 volts 75% terms 90% for derating.
The way it reads I;d say is if you use MV105 the amps are rated at 180.
Question Do all other factors come into play as for Parallel conductors , I know derating goes buy the details (1-2-3 ect).
Needs others opinions .
