A #4 copper conductor with an insulation factor of 75 or 90 degrees C is rated at 85 amps. This size wire will also be the same for a load amperage of 68 amps as the next wire size smaller #6 is only rated at 65 amps.
You can but it would be wise not to. Most 60hz appliances will not work at 50 Hz. <<>> Yes, no problem at all. The frequency does not enter into the equation because the hot plate is a strictly resistive load.
To calculate the amperage at 220V AC for a 24kVA load, use the formula: Amps = kVA / Volts. Therefore, 24kVA / 220V = 109.09A. So, a 24kVA load at 220V AC would draw approximately 109.09 amps.
many wires are. such as 14-2 Romex. 12-2 Romex. Any THHN wire of any size. This list is very long. If you have a speific application then you need to check the NEC 2005 Table 310.13 Conductor Applications and Insulations.
The frequency has no direct relationship to the size of wire. Wire is sized as to the amount of current a load draws in a circuit.
It is possible that the waffle maker will operate on a 220v 50hz power supply, but there is a risk that it may not function optimally or may overheat. It is recommended to check the manufacturer's specifications or contact them directly to confirm compatibility.

If you have a transformer with an output adequate to run the motor, use it directly for the supply to the motor control circuitry. Remember when dealing with motors, the start current will be about 300% of the full load running amperage. Size the transformer accordingly.
Not without spending a great deal of money. Appliances with motors and timers at 50 Hz would have to be changed out to 60 Hz components. Appliances that are strictly of a resistive nature will operate without any problem.
That load would be 10.9 amps.
no load means the motor is acting like a coil

It depends on what the device is. If it is a resistive load then it would act normally. If it was a motor load it would not act as the manufacturer specified it would. The one part that might be a problem is the plug (cap) configuration. European pin configurations are different from those using North American configurations. So to answer the question, nothing would happen because you wouldn't be able to plug a 220 volt 60 Hz device into a 220 volt 50 Hz receptacle.
The motor will run, probably at nearly the same speed, but it cannot supply the same mechanical load. If it can be run on a lighter load, proportional to the voltage, it should be OK.
ONE THING FOR SURE THERE IS NO CHANGE IN VOLTAGE IF SAME EQUIPMENT WE ARE TALKING ABOUT. THE ISSUE HERE IS THE CHANGING LOAD FREQUENCY 60HZ TO 50HZ OR VICE VERSA. FOR EXAMPLE THE MOTOR HORSEPOWER AND R.P.M. WILL BE APPROXIMATELY 90 AND 83 PERCENT OF THE NAMEPLATE SPECIFICATIONS, ALSO THE FULL LOAD RUNNING TORQUE WILL INCREASE APPROXIMATELY 8 PERCENT IF USED FROM 60HZ TO 50HZ.
Balanced load means no unbalanced currents, so the neutral current should be near zero.
f your supply is a Y connected transformer (4 wires COM) with a phase to phase voltage of 380 volts (voltage between any two of the hot wires) , utilizing a true Y connection to your load (connections of one hot lead and neutral for each phase to your load will give a voltage of 380 ÷ sqrt 3 = 380 ÷ 1.732 = 220 volts.
