Yes all breakers will get warm when in use. The full load current of the load flows through the device. Class A breakers current trip rating is rated at 40 degrees C. If in ambient temperatures higher that 40 C then the thermal trip rating lowers. Likewise if the ambient temperature becomes lower the trip rating increases. Sometimes breakers have to be rearranged in the electrical panel to keep high current breakers away from each other. The ambient temperature of adjacent breakers will raise a breakers temperature and cause needless tripping.

Should a circuit breaker get hot on very hot days?
It is normal for a circuit breaker to feel warm or even slightly hot during operation, especially on very hot days, as it is designed to carry and interrupt high levels of electrical current. However, if a circuit breaker becomes excessively hot to the touch or emits a burning smell, it may indicate an underlying issue that requires attention from a qualified electrician.
Why would a 50amp gfci circuit breaker get hot?
A 50-amp GFCI circuit breaker may get hot if it is overloaded or if there is a loose connection at the breaker terminals or in the circuit. It could also indicate a faulty breaker that needs to be replaced. It's important to address this issue promptly to prevent damage or fire hazard.
What would cause a 15 amp circuit breaker to throw after 5 hours?
Operating a breaker on a continuous current, close to the breaker's tripping point can cause this condition. Because the breaker is a thermal device the heat builds up over a time period. Check the breakers on either side of the faulting breaker. If these breakers are also warm from use they take away the heat sink effect and do not let the faulting breaker cool down. Check the current of the load to see how close you are operating to the breakers trip point. Over time the trip setting of the breaker can become lower to a point where it will not reset. Changing the breaker out should rectify this non resetting condition.
How do you find the circuit breaker switch that controls an outlet?
To identify which circuit breaker controls an outlet, plug in a lamp or device and then switch off the breakers one by one until the device turns off. Once the device is off, you've located the correct circuit breaker for that outlet. Alternatively, you can use a circuit breaker finder tool that can help you locate the specific breaker efficiently.
Can I replace a 15 amps fuse with a 15 amps breaker?
I believe that the wires supplying a 30 amp circuit must be at least 10 gauge. If you have 14 or 12 gauge wires going to or from your 15 amp breaker, then drawing 30 amps over it could cause a fire hazard. It's like using those cheapo non-UL certified extension cords to plug a MILLION X-mas lights into (drawing more power than the wires can handle). You also have to make sure this GFI outlet you refered to is rated for 30 amps. Do not simply swap out breakers. Overloading the wires in the circuit protected by that breaker will cause a fire. If you need a 30 amp circuit you must run #10 gauge wire.
Why is heater is not keeping house warm?
A heater may not be keeping a house warm because it is too small for the space. An older heater may not be performing as it should. If you are getting no heat from the heater, you may have blown a fuse and should check the circuit breaker box.

Dryer turns but does not dry?
First thing I'd check is the fuse box. My dryer would sort of warm the clothes, but take forever to dry them. It turned out I had a weak circuit breaker. It would trip, but not vigorously enough to trip the counterpart that was connected to it. It looked like it was on, but it wasn't. Cycling the circuit breakers was good for a couple loads, then it would stop working again. I replaced the circuit breaker and never had another problem.

How can I safely handle a warm electrical outlet?
To safely handle a warm electrical outlet, first turn off the power at the circuit breaker. Use a non-metallic object to unplug any devices. Wait for the outlet to cool down before touching it. If the outlet continues to feel warm, contact a qualified electrician for inspection and repairs.
What is the main function of the magnetic trip in a circuit breaker?
The panel circuit-breaker trips two ways: (1) instant-magnetically; (2) by delayed thermal overload. Instant-magnetically responds to a huge, direct short circuit, where thousands of Amperes may flow immediately. The resulting magnetic field around a hairpin of heavy wire in the breaker pushes the wire arms apart, releasing the latch in the breaker very quickly. The breaker also contains a bi-metalic conductor that bends as it gets hot. If the current exceeds the breaker capacity for a few seconds to a minute the bi-metalic arm heats, bends and releases the latch in the breaker. The thermal-delay allows motors with large startup-current to get running without tripping the breaker. THE REST OF THE STORY: In other words, 20 Amp breaker can supply 40 amps or more for a few seconds. Not enough time to overheat the wire to the outlet, but enough time for a motor's centrifugal-switch to disconnect the start winding. If you overload the circuit a little bit, say 24 amps from a 20-Amp breaker, it will trip, but maybe not for a half hour or hour. On a hot day the thermal release will act more quickly, even though the current will be slightly less because copper wire has a higher resistance when warm.
Why after car is warm looses spark?
Frequently this is caused by a faulty crank angle sensor. As the engine heats up the sensor goes open circuit and there is no pulse to trigger the spark or the injectors. When it cools enough the circuit reforms and the engine will run for a while. Replace the crank angle sensor and the problem should go away.
How can I troubleshoot a light switch that feels warm to the touch?
A warm light switch could indicate an electrical issue. To troubleshoot, turn off the power to the switch at the circuit breaker, then remove the switch cover and check for loose connections or signs of overheating. If you're unsure, it's best to call a qualified electrician for further inspection and repairs.
