Methods and systems for a fire pump control system are provided. An example fire pump control system includes a pump system having a given full load current, wherein the pump system comprises (i) a fire pump, (ii) a first disconnect switch and (iii) a first circuit breaker. The first disconnect switch and the first circuit breaker are located upstream of the fire pump. The system further includes a controller configured to control operation of the fire pump, and the controller comprises a second disconnect switch and a second circuit breaker. The controller is located upstream of the first disconnect switch and the first circuit breaker, and is configured to avoid (i) opening within two minutes at 600 percent of the full load current, (ii) opening with a restart transient of 24 times the full load current, and (iii) opening within 10 minutes at 300 percent of the full load current.
