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.
