The sizing of wire is dependant on what the amperage or wattage of the range is. Most new homes are pre-wired for a standard size range. The wiring is #8 with a insulation factor of 90 degree C and rated for 40 amps. This feeder is protected by a 40 amp breaker.
If the amperage or wattage is larger than this, then a larger conductor must be installed. Use this equation if you need to change wattage into amperage. I = W/E, Amps = Watts/Volts. If the range is in kilowatts multiply the kilowatt number by 1000 to change it to watts to use in the equation.
Use what is called bell wire or thermostat wire.
For that distance I would run AWG # 3 copper and install a sub-panel.
Depends on the wire size you are using. If the generator breaker is a 30 amp then install a 30 amp breaker.
Service entrance wire should be AWG #3 copper.
You need to look at the regulations that apply in your country. If in doubt, use a neutral wire of the same size as the live wire or wires.
Use what is called bell wire or thermostat wire.
For a 30 amp breaker, you will need a wire that is at least 10 gauge in size.

AWG # 6 copper or AWG # 4 aluminum
For a dryer installation, you typically need a 10-gauge wire.
The wire size depends on the amperage, not the voltage. The fact that the welder runs on 440 volts does not affect the wire size! You need to ask this question instead: What size wire do you need for a three phase welder on an eight foot run if the nameplate amps are 45A?
Use AWG #6 wire.
For a 50 amp breaker, you will need a wire that is at least 6 gauge in size to safely handle the electrical load.
The size of wire you need for your electrical project depends on the amount of current the circuit will carry. Consult the National Electrical Code (NEC) or a qualified electrician to determine the appropriate wire size for your specific project.
For that distance I would run AWG # 3 copper and install a sub-panel.
You will need to use #8 wire.
When you buy a install kit you will need a wire kit it comes with instructions do one wire at a time.
