sapphirefountains Fountain Designer used 125 percent of motor FLA as the breaker, which is the NEC 430.22 conductor rule, not the 430.52 breaker maximum. Fixing it changes real outputs: a 5 HP 230 V pump goes from 35 A to 70 A, a 30 A motor from 40 A to 80 A, and one service main goes from 70 A to 90 A. The water_calc AI tool description said 125 percent breaker too.
