A couple things to consider
1. Circuit breakers aren't rated for when they trip, instead they are rated for how much current they will allow indefinitely. That means that you can draw 40A from a 40A breaker for forever. Draw more current than the rating and eventually it will trip but it's a matter of time and how much current you are drawing. A short circuit will have them trip immediately. 45A will take longer. You can look up the data sheet for each breaker and find a graph of when they trip.

Here's the data sheet for our 40A breakers.
