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.
a plateau would be higher
lower
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.
In the Northern Hemisphere the curve would be higher, in the Southern Hemisphere it would be lower.
Higher

Answer"40 C" means 40 degrees CENTIGRADE temperature rating.The breaker is rated to warm up to this temperature while in use without risk of fire or breakdown. It should not be used in such a way that it exceeds that temperature.Note that wires connected to the breaker must have an equal or higher temperature rating of its insulation. However, when the wire insulation rating is greater than the breaker rating, the wire's capacity must be determined using the breaker's lower temperature rating.For example:If the breaker is 400C and the wire is 400C, the wire capacity would be based on 400CIf the breaker is 400C and the wire is 600C, the wire capacity would be based on 400CIf the breaker is 600C and the wire is 900C, the wire capacity would be based on 600CI don't believe this to be true... The breaker is tested to and calibrated at the 40c rating. (This has more to do with ambient temp. than the way the breaker is being used) In a case where the temp. may exceed this rating you may trip before seeing the current the breaker is rated. The wire is typically rated @ 75c & 90c and the connection point on the breaker or the lug would be rated @ 60cThe above paragraph is correct It is the ambient rating of the breaker calibrated to trip at that temperature set point. In cold climates this has to be watched very closely. On a -20 C day, on breakers that are exposed to the elements, a breaker on the overload portion of the tripping mechanism may not trip until the current reaches one and a half times the handle rating.
