Actual voltage would be 240V. 4 AWG copper is capable of carrying 50A. At 200 ft, with a 50A load, voltage drop would be about 6V, which is within the acceptable 3% voltage drop for a branch circuit.
To calculate the wire size, a system voltage is needed.
10 amps is the maximum it will carry.
10 awg wire can have a breaker size of 30amps. It can actually carry more but as for codes the wire is usually allowed to carry 80% of its max capability which puts the breaker at a max size of 30 amps.
This is a voltage drop question. To answer the question about distance a voltage must be stated. That said a #10 copper conductor with an insulation factor of 75 or 90 degrees C are both rated at 30 amps.
#6 AWG50sqmm Al cable can carry 60 amps safely up to 150mtrs. If distance increases size should increase
To answer this question a voltage must be given.
Depends upon the voltage. The formula for amperage or (wire size) is Watts / Voltage. If the voltage is 220 volts, then the amperage would be over 400 amps. This would require a large wire size to run it. If it were 440 volts, the amperage would be 1/2 or 200 amps. That would require a smaller wire size. As the voltage goes up, the amperage goes down. At a thousand volts, the amperage would only be 90 amps. A wire gauge or size of a #2 would carry 90 amps for small distances.
To calculate the wire size, a system voltage is needed.
Wire is sized by the amperage that it will carry. 5 kW is 5000 watts. The equation to find watts is W = Amps x Volts. The equation to find amps is Amps = Watts/Volts. As you can see a voltage is needed to calculate the amperage. Once the amperage is stated, the wire size can be given for that particular amperage.
A # 14 copper conductor will be fine to carry 8 amps at 120 volts. This size conductor is rated at 15 amps.

This is a voltage drop question. To answer the question about distance a voltage must be stated. That said a #10 copper conductor with an insulation factor of 75 or 90 degrees C are both rated at 30 amps.
To answer this question a voltage and amperage must be stated. W = Amps x Volts.

The V stands for volts and A is amps. If for example you have a 12kVA device and are running off a voltage of 120 volts then Amps = 12000/120 = 100. You then use the calculated amps in a wire size table to get the correct size.
