With the given compressor torque the minimum tapping to guarantee a safe start is 85%. The starting current from the network is then reduced by a factor of 0,852. For a motor with 6 x In (Nominal Current) at start this means the network starting current is about 4,3 x In. Assuming a rated motor current of 521A this gives 2240A network current which is 200% of rated generator current (3 x 377A).
