Okay, it is most definitely a standard circuit breaker. It instantaneously trips on anything over 100 amps. The first few tries probably started to raise the impedance of the sub so it eventually worked on the 6th try. Still though, taking impedance rise into consideration, it wasn't 11 kW. In any case, I'm going to sleep and I'm going to stop dwelling on this for no reason. I have a full day tomorrow of testing transformers, breakers, switches, starters, and drives as well as putting together reports on my findings.
