Depends on the wire size you are using. If the generator breaker is a 30 amp then install a 30 amp breaker.
Answer for USA, Canada and countries running a 60 Hz supply service.It is not a recommended procedure. Depending on what size service entrance cable it is the wire size will be too large to fit into the breaker and range lugs. Cutting strands off of a larger size wire to fit into the lugs is not acceptable. If this is new construction then the electrical inspector will reject the installation for not using the properly sized cable to feed the range. Use the proper size cable and feel free that there is not going to be any problems further on. The wire should be 3 conductor #8 fed from a two pole 40 amp breaker.
25 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.
Incomplete data: To have an accurate result - please provide the following; 1. Voltage Rating - Low Votage or Medium Voltage Applications? 2. Efficiency 3. Power Factor 4. Distance - One way distance from source 5. Location and method and arrangement of Installation 6. Allowable or acceptable voltage drop 7. Type of cable - PVC or XLPE cable with same size has different ampacity
For a 3KW motor with a 350-meter run and 240V supply voltage, you would typically need a cable size of around 16mm² for proper voltage drop considerations and to prevent overheating. It's recommended to consult with a qualified electrician or use a voltage drop calculator to determine the exact cable size needed for your specific installation.
No, a 10mm cable should be used with no more than a 40A breaker for typical household wiring. Using a 10mm cable with a 50A breaker can lead to overheating and pose a fire hazard. It's important to follow the proper cable size guidelines to ensure safety.
4sqmm
The largest size of twin and earth cable available is typically 16mm² in the UK market. This size is commonly used for higher current applications such as cooker circuits or shower circuits.
size 6 rings start at 10 then just add the size to it,lets say its a size 6 so,10+6=16mm
The biggest circuit breaker in any home is the main breaker located in your main breaker panel that is installed where your electrical service cable comes into your home.
16mm
The wire is sized to the maximum overcurrent protection device (Max circuit breaker) ampacity. This is listed on the nameplate of the outdoor condensing unit. Size the wire to match the breaker.

I would use a 5/8 drill bit which is almost exactly 16mm.
