I am not familiar with the electrical laws of Dellis which is why I simply don't know...Can I legally run 2 - 230 single phase hand dryers from one 230 volt 3 phase tap dryers pull 9.1 amps tap rated at 20 amps.
That drops to 50% for "utilization equipment fastened in place, other than luminaires" if the branch circuit in question also supplies an outlet and or luminaire. May not be the case here, but one never knows.#2 you can only load a circuit to 80% of its capacity, 9.1 X 2=18.2 > 20 X .8=16.
