Hi,
Let us calculate.If it is British HP i.e. P=3x745.7=2240W=2.24kW.If the named current In=9.6A i.e. motor ir star-connected(In=P/3xUnxcos phi x eff).I don't know cos and efficiency. Calculate please and You get approximately refered result.For delta-connection motor's current (in windings)...
Hi,
It's be good to get more details (motor's power, connection,start and working currents,time of start).If it is enough big motor with delta-connected stator, perhaps is it need to use soft-starting system or star-delta reconnection? I think such solution's realization will have
the lower...
Hi,
I bag Your pardon.I forgot, that we are talking about US. For American application it is necessary to montage protection on two wires.I must suggest with Controlman and Chris33.

Hi,
Comment:One phase motors usually are coonected with three wires-first is line (phase),second-neutral, third-ground.
It's enough to montage a protection device (from short-circuit connection ,overload, maybe also with earth-leakage relay) on the line wire.
