If specs on a 300Hp electric motor;(adsbygoogle = window.adsbygoogle || []).push({});

480 Volts

3 Phase

60Hz

The full load Amps of the motor is 361A, which I found in the NEC table. My distance is 700ft to a control center and I can't seem to figure out what copper conductor size to use. In order to find the Voltage drop I have to know the CM, I assume. Can any one help me with my design?
