How many #12 thhns can u have in a 3/4 inch emt current carrying conductor wise?i thought because the actual ampacity capacity of a number 12 thhn was 30 amp but not to have over-current protection above 20,but u could still.factor in the 30 for derating purposes so u could use the 70% ADJUSTMENT FACTOR and still fit 9 in.
