Okay, I see a potential conflict in these two sections and I would like to have it clarified. In NEC 422.10(A) it state's:
Individual Circuits. ...The branch circuit rating for an appliance that is a continuous load, other than a motor-operated appliance, shall not be less than 125 percent of the marked rating,...
By branch circuit rating I assume they mean the OCPD? Or perhaps the conductor sizes? In NEC 422.11(E)(3) it state's:
If the branch circuit supplies a single non-motor-operated appliance, the rating of overcurrent protection shall comply with the following:
(3) Not exceed 150 percent of the appliance rated current if the overcurrent protection rating is not marked and the appliance is rated over 13.3 amperes.
Now in both cases it seem's to apply to the same type of circuit and the same type of appliance. Question: How is the OCPD sized? In one case it's at 125% and in the other it's at 150%.
