If you have one feeder supplying two motors one 10HP and 15HP @ 480V, so when determining the feeders you would multiply the largest motor by 1.25 and then add the other FLA for a total of 40.25A, since there is one conduit feed would you derate by .80 for more than three current carrying conductors in the raceway and figure the conductors for 50A?
