I always thought that the code language in 510.125(B)(3) was clear that you could use a TEFC motor in that classification. (with attention to the ignition temperature of the products involved and the operating temperature of the motor)
I was at a presentation from a GE application engineer yesterday, and his position is that any motor used in that classification must be specifically approved by the motor manufacturer for that use.
