adding 3PH Motor onto Panel Schedule 1

[AdeptGino]

So basic question. 3PH, 208VAC, 10HP motor. .75KW per HP, so 7500W Motor.

How do i put this onto the panel? Is it phase A, B, C, = 7500 OR 7500W/3 and A,B,C = 2500W on the three phase of the panel.

Thanks.

Yes, 1/3 per phase, but you need to find the motor full load amps for accurate load and sizing. Your calculation is neglecting power factor and efficiency. 1 kVA per horsepower is a better approximation.

Divide the load kW between the 3 phases.

*dpc strikes again!*Certainly, his advice is the most accurate.
