WHY TWO DIFERENT RATING FOR FIRE PUMP?
(OP)
I have just read someone’s design drawing for a 30 Horse Power Fire Pump. I am not sure why his design calls for 250 amp enclosed circuit breaker on the Normal side of the Fire Pump controller ATS on the Normal side and a 50 amp enclosed circuit breaker to the Emergency side of the Fire Pump controller ATS.
I am not sure why this two different rating for Normal side and Emergency side. Can someone explain this concept?
