Need more information. It doesn't seem rationale that they are protecting the same circuit unless you are substituting one for the other for a test. A unit like an air conditioner may have multiple breakers and a higher value breaker may trip because the load it is connected to is drawing current in excess of the rating of breaker.
A 15 amp breaker will trip at 15 amps at an ambient temperature of 104 degree F. If the ambient temperature is higher the breaker will trip before 15 amps and if the ambient temperature is lower the breaker will trip after 15 amps. I would suspect the circuit is overloaded. But, you can change the breaker and see what happens. Just swap it with another one.
If the dewpoint temperature were lower, the height of the cloud base would generally be higher. This is because the air would need to cool further before reaching saturation, allowing clouds to form at higher altitudes. Conversely, a higher dewpoint temperature would lead to a lower cloud base height.
The voltage before the breaker is from the distribution panel's buss bars. This voltage is controlled by the panel's main breaker. To have no voltage on the terminal of the breaker means that either the breaker is shut off or it has gone into a trip position. If it has tripped push the handle of the breaker to the off position and then to the on position. This should reset the breaker. If the voltage is not present at the output terminal of the breaker after resetting it, then replace the breaker as it has a fault in it.

Higher.
A 30 amp breaker is designed to trip at an earlier point than a larger 40 amp breaker so one appliance that operates on lower amperage level could be unsafe or damaged before it could trip the higher 40 amp breaker. Also, the existing wiring may not be rated for 40 amp service.
Higher
faster in higher altitiudes
In the Northern Hemisphere the curve would be higher, in the Southern Hemisphere it would be lower.
faster in higher altitiudes
Well, if you're asking which is lower, It would be 32.45. If higher, 32.6. Hope this helps!
