Wire sizes are based on amperage. To find the amperage of a 8 kW or 8000 watt strip heater the following formula is used. I = W/E. Amps = Watts/Volts, 8000/240 = 33 amps. Legally and the electrical code stated that conductors can only be loaded to 80% of their rated capacity.
A #10 copper wire with an insulation rating of 90 degrees C is rated at 30 amps.
A #8 copper wire with an insulation rating of 75 or 90 degrees C is rated at 45 amps.
Calculating a #8 wire, the ampacity is 45 amps x .80 = 36 amps. The load only draws 33 amps so it looks like your feeder size for the 8 kW heater will be a #8 with an insulation factor of 75 or 90 degrees C.

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.
It really depends on the size but the average is about 24 volts.
This question cannot be answered because you did not specify the current.
To answer this question a voltage needs to be stated. Wire is sized by the amount of amperage the load takes. W = Amps x Volts. Amps = 650/ volts.

Need to know what the size of the wire is in the coil and the physical diameter of the coil.
A healthy heart should be about the same size as the owner's fist.
SOOJW is limited to 300 volts and should not be used on 480 volts
You physically can but sit will be unsafe, and will not protect the circuit because it will not blow when it should. Only replace a fuse with the same size fuse.
Depends on size.
About 400 volts to 650 volts. Depends on the size of them as well.

Usually 30 Amp 240 volts, but there will be a spec on the well pump.
It depends on the type of system that is used to heat the incubator. State the heating element size in watts or give the volts and amperage of the unit.
