Thanks for the correction on stall current. I was honestly just guessing on the number because I couldn't easily look it up, but I knew it was well above 40A.
Anyway, I've been an inspector multiple times over the last 7 years I've been volunteering and have had to tell teams to change where CIM motors could be wires. This means it was on the inspection checklist, which means there was a rule for it. You may be true that there was no explicit list of what motors could be connected to what breakers, but there has been a rule in the past that said what breaker a CIM had to be on. I just woke up, so I'll update this comment as soon as I'm coherent enough to go find a source.
