Conductor sizing for sub-panel

[csoc64]

Installing a 60A sub-panel off of an existing 200A panel. Am I correct that #6 THHN copper conductors are adequate? I am using the 75 degree column of 310.15(B)(16) due to termination temp limitations. Looks like I'm good for 65A.

FMC

Its good for the 75 degree column. Romex however would not go past 60 degrees

With FMC and THHN conductors, #6 AWG on a 60 amp OCPD is fine. You could go up to a 70 amp OCPD if the load were 65 amps or less.
