mc cable

[Treg the electrician]

does mc cable fall in the 60 or 75 degree column i couldnt find it listed in 310.16 someone told me it was 90 degree column but i just want to know for sure

90° C for derating purposes and 75° C for ampacity. For example with 75° C terminations, a #8 AWG MC cable can be protected at the 75° C ampacity of 50 amps.
