If you are running 10ga why would you ever use less than a 30a breaker on a
motor load?

Me? Like I said, I'll 'over-engineer' the physical -- the cost difference
is minimal, and it provides additional flexibility for 'later'.

At the same time -- and particularly for 'dedicated' applications -- I tend
to match the breaker 'as closely as possible' to the _actual_ load. So that
it trips 'as soon as possible' in case of device excursion into "abnormal"
territory.
Call it 'defense in depth', against Mr. Murphy. grin
