Michael, a motor as defined in 430 requires 125%. The fact that it is an appliance does not matter since it it a motor operated appliance.Dennis & Kwired, the question is: is this motor operated appliance (dust collector) considered continuous or other than continuous duty? Section 430.22(E) states if "Other than Continuous Duty" it does not need to be wired at 125%.
Here is the other point to consider. YOu told me that the wiring method is nm cable. Under the 2008 NEC 12/2 NM is rated 25 amps so you could install a 25 amp breaker and it would be compliant. Under the 2011 it would not be.
