Greg, thanks for bantering back and forth with me. In this case, this 400A panel is also serving a number of small loads. The 30HP elevator controller is of a soft start type, but this manufacturer would not recommend a size breaker to feed the unit. I sized the the breaker based on 430.52(C)(1)excpt.(1). I was trying to avoid buying a panel that would handle a 200 or 225A OCPD feeder/branch device(puts you into a higher end panel) since I had to shunt trip anyway. This elevator moves people primarily.
