Re: Fisher Price Breaker Size
We are using 40 amp breakers on our FP motors because there are times when we want that extra power kick. The FP motor can handle 40 amps but only for short periods of time at high RPM. We know we could conceivably burn up a few if something goes wrong (gearbox jam, stall, etc).
More important than breaker sizing is watching your loads. FP motors have a very distinct smell when they burn up (the insulation on the motor windings burns off). The first time you blow one up, you won't forget it.
Watch your loads! Don't rely on the breaker to save the motor.
