We have an electric motor driven pump controlled by a VFD. The pump's HP rating is about twice what the process requires. So, while we might normally install this pump on a 600 amp breaker, we don't expect to ever draw near that amount. The installation location cannot supply the 600 amp circuit. Can we use a smaller breaker at the main distribution panel? If so, can someone point me to the code section(s) that might point this out?
