If the new one is 22.0a and your running it on 20a breakersi just replaced pool pump motor (ao smith)new one keeps tripping breaker box, only difference is old motor max amp was 18.6/9.3 and new one is 22.0/11.0 , the breakers are two 20 amps, is this my problem, do i need bigger breakers?
But it would have to be way higher (at least 30-40A) to trip it instantly. An 11A centrifugal pump motor really should start on a 20A breaker.Even at 11a, if it is just the running current,
This could mean a starting current that could easily exceed 20A.
Unless it is a time lag breaker.
