Depends on the wire size you are using. If the generator breaker is a 30 amp then install a 30 amp 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.
In North America the standard sizes for breakers are 15, 20, 30, and 40 amps. The 15 amp size breaker is used in general circuit wiring. The 20 amp size breaker is used for dedicated appliance receptacles, hot water tank and baseboard heating. The 30 amp size breaker is used for a clothes dryer. The 40 amp size breaker is used for the electric range.

A 100-A sub-panel would be fed from a 100-A breaker.

The 225 amps is the secondary output amperage. Look on the machines nameplate to find the input amperage. It is that amperage that is needed to size the feed wire and there the breaker size. When you find that amperage you may want to re question the breaker size.
The formula you are looking for is I = W/E.

To determine the size of the breaker needed for a 78 amp range, you typically need to use a breaker that is the next size up from the amp rating. This means that you would need an 80 amp breaker to safely accommodate the 78 amp range. However, always consult with a qualified electrician to ensure the correct breaker size for your specific electrical setup.
For a standard size refrigerator, a dedicated 15 amp circuit is used.
For a 41 amp load, you would typically use a 50 amp circuit breaker. The general rule is to select a breaker size that is 125% of the continuous load amps or equal to the load amps if it is not a continuous load. In this case, 41 amps is considered a continuous load, so you would round up to the nearest available breaker size, which is 50 amps.
A minimum of 15-amp breaker is "needed", but a 20-amp is often required by electrical code for that situation.
