hi there,
Looking for some info, on how i would find the current draw of a 2 Hp motor running at 208v 3 phase with a unity power factor and efficenty of 100%. I can't seem to put it together today and cannot get ahold of a TA, basically i need to size wires/fuses in a schematic for this current draw and completely forgot how to do this. I keep getting 862 A which i know is way too high. I know 2 hp = 1492 watts. Can someone please help me with the mathematic breakdown? Would be appreciated.
i think I am losing it been a real bad week for me.
I think can use this:
P(watts) = I(Amps) * v(volts)
1492 = I * 208
I = 7.17 A per phase?
Is this correct?
Thanks,
Matt.
