I have one issue with your otherwise excellent post -- this last sentence:

And as has been a couple times, the breaker provides short circuit
protection for the wire, not overload protection.

The breaker provides *overcurrent* protection for the wire -- IOW, the breaker
is sized to open if more current is flowing through the wire than it can
safely handle. This does not occur solely through short circuits, but can
result from overload as well (e.g. fifty 60W incandescent light bulbs on a
single 15A circuit is supposed to pop the breaker, even though there is no
short).



This is a motor circuit, not light bulbs. The rules are in article 430.



Right, I know -- I'm objecting to what appeared, at least, to be a general
statement that breakers provide only short-circuit protection. In the specific
cases you cited, that's correct, but as a general rule, it's not.


My post was in the context of motors.

Your response was general - it would have helped if it was limited to
non-motors.
