A 'molded case circuit breaker' is a common designation for the circuit breakers used in the main electrical panel of most American homes.
The name is meant to infer that it is designed to never be opened, repaired, or modified. Replacement is the only option.
They are completely different. A moulded-case circuit breaker is a low- or medium-voltage device, whereas an air circuit breaker is a very large circuit breaker designed for use in high-voltage transmission/distribution substations.
You need to be more specific. Do you want a contact telling you if a circuit breaker is on? If that is your question, the answer depends on the model of the breaker.
Circuit breakers do not have circuit diagrams. The breakers have an input where the distribution voltage is applied and an output where the load is applied. If you want to know what is inside a breaker, the electrical terminology to use is "shop drawings" of the specific breaker that you need information on.
you can use a fuse or circuit breaker
Generally a circuit breaker (like a light switch) But I guess you could use a resistor of the right resistance If you are talking about the circuit breaker there is an electromagnetic coil in it which get magnetized on a specific amount of current and breaks the circuit

No, it is not recommended to have a circuit breaker with a higher amperage rating than the device it is protecting. In this case, you should use a 30 amp circuit breaker for a 30 amp air conditioner to ensure proper protection from overcurrent.
An alternative to using a fuse is to use an electrical circuit breaker.
No, a 27 amp start-up on a 15 amp circuit breaker can potentially overload the circuit and cause it to trip. It's recommended to use a circuit breaker that can handle the full current draw of the device to prevent tripping and ensure safety.

Yes, but I would not recommend it if you are constantly turning the power on/off. If that is the case install a disconnect.
There are various to check if your air circuit breaker working. You can use various tools that are available to test your air circuit breaker. A clamping ammeter is ideal for this purpose.
To test a circuit breaker, you can use a multimeter to check for continuity and proper voltage. First, turn off the power to the circuit breaker. Then, use the multimeter to test for continuity by placing the probes on the terminals of the circuit breaker. If there is continuity, the circuit breaker is functioning properly. Next, test for proper voltage by turning on the power and checking if the voltage is within the specified range. If the circuit breaker passes both tests, it is functioning properly.

For typical residential house wiring 12 AWG wire is required for a 20 Amp breaker. If you change out the breaker for a 25 A breaker you would have to rewire the circuit with 10 AWG. In that case you could up the breaker to 30 Amps. All outlets and switches should be rated at the same voltage and current as the breaker.
The size breaker you use is determined by the size wire used in the circuit. If you use AWG #12/2 wire then use a 20 amp breaker. If you use AWG # 14/2 then use a 15 amp breaker.
