I had a call to replace an FPE three pole 40 amp NA breaker at an gas station with an 5 ton Rooftop A/C Unit. There had been an tranformer taken out by a cehicle that caused an Power Outage. When they tried to reset the tripped breaker the Breaker would not reset. What would cause the problem?...or the short circuit caused magnetic forces to mess with function of breaker? The new Breaker flipped on and everything was fine.
