That's not a Jaguar issue. It'll happen if you put too much load on the circuit no matter what speed controller you use (or don't use). For example, our propeller gearing is slightly off optimum, and at full power the motors want to draw more than 40 amps. We have to throttle them back to keep from tripping the breakers. Incidentally, they are controlled by Victors.

Jaguars do have their own built-in 40-amp limit, and will shut down for several seconds if that limit is exceeded, independent of the circuit breakers.
