430.109(B) of the 2005 NEC:


Stationary motors of 1/8 HP or less For stationary motors of 1/8 HP or less, the branch circuit overcurrent device shall be permitted to serve as the disconnecting means.

This supprised me a little, because I know I've used the branch breaker for the motor disconnect for larger motors when the panel is near the motor.

So the question is: Does this prohibit a the branch breaker from being used as the disconnect for a larger motor??

I can't understand why there are paragraphs in the NEC that tell me what I can do, and don't say anything about what you can't do.

Maybe I should rephrase the question:

Does anyone know of anything in the NEC that prohibits the branch circuit breaker from being used as the motor disconnect for say a 1/2 HP motor?
