Re: Fisher Price Breaker Size

A proper mechanical design should never trip it's breaker unless a very abnormal condition exists. Take a look at the motor curve, see what torque the motor can produce at the current your desired breaker can supply, and design your system for the motor to be loaded less than that.

I traditionally try to use the largest breaker allowed, since it will result in being able to run your system with a higher load on the motor.
