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.
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.
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.
If you want an American plug to power a 30A 220V device look at a dryer outlet. It will have an extra neutral conductor, but it is standard. Otherwise, you can go with a 220V 30A TwistLok plug. All the home centers [I've been to] carry these plugs. 10ga wire is heavy enough for 30A runs under 75ft, though for a 27A appliance you should consider a 40A breaker with 8ga wire.
10 AWG.
Identify the neutral wire on the generator. This will be the unused conductor to run the compressor. The ground and line1, line 2 are all that are needed.
To create a Crossover Cable, wire one connecter to the T568A Network Standard and wire the other connector to the T568B Network Standard, so the cable 'crosses over', A becomes B and visa versa.
This might be a cable for some additional feature your car is not equipped with, but the wire is included in the standard cable assy

No it is not
Electrical range is usually 220V and requires at least a 40A breaker. In a three wire configuration, the white power carries 110V, the black wire carries 220V and the green wire is the ground. A four wire configuration has an additional wire that is neutral.
There comes a time when you simply have to upgrade your electrical service. A 60hz service was never designed to handle all the power requirements of a modern home. When the 60hz service came in, it was designed to handle a few lights and a few receptacles. I'd be surprised if you had more than 4 circuits on your board and I'm betting that you are blowing fuses or tripping circuit breakers constantly. Bite the bullet, upgrade your service.

Amperes is not constant like voltage. You can have .01 amps or 1200amps on a wire. Basic sizes of cable and their amp limits (for residential usage): 14ga. 15amps, 12ga. 20amps, 10ga 30 amps. It doesn't matter if its on 110V or 220V
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.
In a DC circuit it is positive. In a 220v ac circuit it's one of the two positive (hot) lines.

In North America you would use a three wire cable. A dryer needs two voltage supplies. A 240 voltage for the heating element and 120 volts for the motor and controls. The three wire cable will have a ground wire in it also but in North America this is not counted as it is not a current carrying conductor. The size of the cable will be a 3C #10.
