A conductor carries the voltage potential from the source to the load, i.e. the wires from a circuit breaker to a light.
A breaker is sized by the conductor that is connected to it but also the load that is connected to the breaker. There are some cases such as motor loads where the breaker has to be 250% of the motors full nameplate amperage.A #4 aluminium conductor with an insulation factor of 90 degrees C is rated for 75 amps.
A breaker is sized by the conductor that is connected to it but also the load that is connected to the breaker. There are some cases such as motor loads where the breaker has to be 250% of the motors full nameplate amperage.A #6 aluminium conductor with an insulation factor of 90 degrees C is rated for 55 amps.
If it is a portable generator the breaker should be self contained within the generators panel. If the generator is a stationary standby unit a voltage has to be stated to calculate the conductor size and hence the breaker size to protect the conductor. Amps = Watts/Volts.

A #12 copper conductor with an insulation factor of 90 degrees C is rated at 20 amps. A #14 conductor can not be connected to a 20 amp breaker as that conductor is only rated at 15 amps.

No, it is not safe to use a #8 conductor on a 50 amp breaker. A #8 conductor is only rated at 45 amps capacity. By connecting it to a 50 amp breaker, which would trip at 50 amps on an overload, would overload the conductor by an extra 5 amps. This would be a conflict against the electrical code.
Youcan butyou shouldn't. A #12 copper conductor's rating is20 amps.The overcurrent protection on the branch should be LESS than the ampacity of the smallest conductor. That way, the breaker will blow before the wire gets red hot, damages its insulation, or causes a structure fire.
If it is a portable generator the breaker should be self contained within the generators panel. If the generator is a stationary standby unit a voltage has to be stated to calculate the conductor size and hence the breaker size to protect the conductor. Amps = Watts/Volts.
Typically the black wire is "hot", and the white wire is neutral. A 2 pole breaker is most commonly used for 240 V, and as such, you would typically use a 3 conductor wire, with black, red and white (+ ground). In a typical application, the black and red are used in the 2 pole breaker, and neutral is connected to the neutral bar in the breaker panel.
Yes, the rating of a 3 pole circuit breaker is the same for each conductor that is connected to it. A three pole breaker rated at 30 amps will have 3 #10 wires from it that connect to the load.
