You could use a transformer in theory if a 200 volt ac unit is single phase. You must mean a 220 unit. 120 uses 3 wires, hot neutral and ground. 220 has two hots a neutral and a ground. A 2 phase motor is more economical than a single phase motor. That is why all larger units are 220. I have seen people change the breaker to a 220 and use the ground as a second hot to avoid the cost of rewiring, but don;t do it. It is against building codes ,and you don't want to break the law, not to mention it is a fire hazard. Long story short, how can I use an appliance made for 220 with a 120 source, you can not. The larger unit draws more current than a 120 can supply. If you found some way to wire it the wires will heat up and if your breaker fails you have a fire.

Yes, but it will not work.
Yes <<>> In North America, a three wire 120/240 volt system uses a neutral wire. For 240 volts two "hot" wires are used with no neutral.
The wire sizing of any equipment is related to the amperage that the equipment draws. Look on the air conditioner and restate the question and give the amps that the unit uses and at what voltage.
Answer for USA, Canada and countries running a 60 Hz supply service.A three wire installation provides a power source for independent 120 volt circuits and 240 volt circuit with neutral.A common 120/240 volt 200 amp distribution service panel can have 42 circuits supplied from it. These circuits can be in any number of different combinations of 120 volts or 240 volts.
In residential wiring the white wire is neutral on the 120 volt circuits. On a 3way circuit the red is the traveler and the white is neutral. On a 240 volt 3 wire connection the white & black are hot. On a 240 volt 4 wire connection the black and red are hot and the white is neutral.
If it is a 240 volt conditioner it will stop. If it is a 120 volt conditioner it will stop if it is on the leg that has been lost.
Yes, but it will not work.
No, not a good idea. You have to use a 347 volt ballast.
black
yes
Only if the cable going to your well pump is a three wire. The third wire could carry the neutral and you will have 120 volts from either 240 leg to the neutral.
Should be about 120 VAC.
You can't. The 120 volt GFCI is probably just a 2-wire (hot, neutral and ground) You would have to run a new 3-wire (2 hots, neutral and ground). The two hots are how you get the 240 volts (120+120=240). Also you must make sure the wire is gauged properly. #10 wire for 30 amps, #12 wire for 20 amps, etc.

In the US of A, it's supposed to be black.
AWG # 10 wire on 30 amp circuit.
Wire is wire - is doesn't matter what voltage you use. However, if you are changing the voltage on a device from 240 to 120, given the same power requirement, you may need bigger wires for the doubled current (and increased heat of resistivity).
