Jim, I'm not really sure what your post is trying to say.

The FPs must be connected to a speed controller based on rule <R54-A> (as Eric mentioned).

These speed controllers can then be connected to 20, 30, or 40 Amp breakers. The required wire gauge is based on the breaker used.

If someone wants to run an FP off a 20 Amp breaker they would be allowed to do so. They could then use wire as small as 18 gauge to wire this branch. Depending on where on the torque/speed curve the motor is being run, this may or may not produce desired performance, but it is perfectly legal.

In fact, you could wire your CIMs through 20A breakers if you wanted (note: this is almost certainly a bad idea)
