if i have 6 number 12 thhn/thwn wires in a 3/4 inch emt conduit, am i o.k before i have to derate based on more than three current carrying conductors in a conduit you apply an adjustment factor 4-6 conductors 80%,7-9 conductors 70% table 310.16 has #12 at 75 deg is rated for 25amps,
so 25amps*80%=20amps will six be o.k in the 3/4 emt conduit before i have to go to the next size wire up.
