Hello, how do drivers for fire pumps in NFPA 20 sprinkler installations have to be sized correctly? Do the drivers have to be sized only up to the 150% of the rated flow or do the drivers have to be sized to the non-overloading power consumption point which is tested/examined at fire pump such as FM approval or UL listing?
