I would agree with George that motors are not considered continuous loads. 215-2 indicates feeders to be noncont + 125% cont. However, for motors, circuit conductors can be sized per 430-24, 125% of largest motor + fla of all other motors + other loads. 430-62.A talks about feeder protection which is 430.52 ofr largest motor + sum of other motors. 430-62.B references 430-24. 430-63 also references 430-62. Based on the above, conductors and ocp for motors are sized diferently than other loads, and not sized as continuous loads, at least not in the literal sense that we are used to sizing for continuous loads.
IMO.
