15 amp breaker continuous current

I had a master electrician test recently and there was a question I was unsure of.

How much is the max current you can run on a 15 amp breaker continuously? I thought those breakers were not rated for 15 continuous But couldn’t ding reference

What is the maximum motor current on a 15 amp breaker.

If connected to a continuous load the CB is limited to 80% of its rating.

I thought that was true do you k is the code reference I have had no luck

Correct me if I’m wrong 210.20(A) may answer both my questions. Motor is continuous load

the overcurrent device shall not be less than the non continuous plus 125% of the continuous load.

unless the CB is 100% rated. I don't think there are any 15A 100% breakers though.
