I need a little clarification here. I have a 3 phase 5hp 208v motor. According to 430.250, the FLA is 16.7a. The conductors shall have an ampacity of 20.88a per 430.22 which would put me up to #10awg. The OCPD could be as high as 40a per 430.52. I am assuming from this that it would be legal to put #10's on a 40 a breaker for this motor circuit. I realize that 430.52 is a maximum value so would it be ok to use a 30a breaker if I chose to in this situation?
