For example, a fisher price motor can draw more then 40 amps at stall, but it will also burn itself up at stall. It may be wise to use a smaller breaker.
You are indeed correct. The circuits on 20, 30, and 40 amp breakers must have appropriately sized wires, but there are not, as in the past, requirements that CIM's and FP's get 40A, and everything else is 20/30A.
