We used to have a turbopump that would trip the breakers every time you turned it on from cold. The pump seemingly attempted to spin up to max RPM before settling down to a more sustainable load. The only way to get the thing to stay on was to turn it on once, let it warm itself up on the initial attempt, trip the breakers, and try it another cycle now that it had some momentum and would pull slightly fewer amps. Sometimes took a few attempts to get that rolling start working.
