Depends on the wire size you are using. If the generator breaker is a 30 amp then install a 30 amp breaker.
You have a double pole breaker for 240Volt supply. The maximum current is 15 amp.
Use a 30 amp breaker.
Not unless the wire going to the refrigerator outlet is AWG 10/2. If it is wired with 12/2 wire then you must use a 20 amp breaker. Using a 30 amp breaker is dangerous and a fire hazard.
A 30 amp breaker run 75 feet would require you use AWG #10 wire. But, an oven normally pulls more that 30 amps and I would not use #10 wire on a 30 amp breaker for an oven. Normally any newer oven is wired with AWG #6 gauge wire on a 50 amp circuit breaker so the breaker will not trip during heavy use of the oven. Some older ovens could use a #8 wire on a 40 amp breaker.
Replace the 30 Amp Breaker with a 15 Amp breaker.
Yes, a 30 amp breaker is a 30 amp breaker. It must however be able to fit the box it is installed in.
If it is a 30 amp breaker then it is a 240 volt outlet.

Yes.
Use a 30 amp breaker.
30 amp breaker with #10 gauge copper wire
10 amps
Not unless the wire going to the refrigerator outlet is AWG 10/2. If it is wired with 12/2 wire then you must use a 20 amp breaker. Using a 30 amp breaker is dangerous and a fire hazard.
yes, you can attach. but if the current through the line i.e. through the breaker exceeds 20 amp the breaker will trip. As long as the line carries 20 amp or less there is no problem.
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.
