The question is what is "properly".

There may be a more scientific method, but that's what I have always seen.
Even the adjustable breaker on 150 HP pumps are often set by "experience".
Set it just high enough for normal operation, and if it ever fails
prematurely just bump it up a little.

Makes sense. This is not life support equipment. If the overload pops
one day when it should not have, not the end of the world.
