When applying correction factors per 725.51 to control cables if the amps exceeded 10% of the rating of the conductor you have to use 310.15(C)(1).
Say you had 10 control cables with just ONE circuit over the 10% of a #14Awg, (e.g 2Amps) you’d derate per the total of 10 current carrying conductors or 50%.....Or should it be if all 10 conductors carry +1.5A then you’d factor by 50%?
