Does it have a name plate or instructions on how to wire it? the wire that you pulled black,red or red ,blue goes to one of the fixture leads and the other color to the remaining fixture lead. green to green for your grounding conductor. As always if you are unsure consult a qualified person in order to be safe!
It could if you don't get the terminals and motor wires on the correct terminals.
It depends on the voltage, but if you are using it on a 240 v system, it's quite OK to use wire that can take 600 v (if you had to buy the wire, you would be spending too much).
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.
A 240-volt circuit typically consists of two hot wires and a ground wire, with no neutral wire. The hot wires each carry 120 volts, while the ground wire is used for safety purposes. In a 240-volt circuit, the hot wires complete a loop by connecting to a load or device that requires the higher voltage to operate.
The metal halide light is a commercial fixture. Wire it to 120 volt. 277 volt is the star point voltage of 3 phase 480 volts. Likewise 347 is the starpoint of 3 phase 600 volt. By wiring it to 240 volts the voltage might not be high enough to ignite the lamp. Try it and see, it won't do any harm to the fixture. Make sure that the wires that are not connected are taped off as there will be voltage on them.
A 240 volt street light circuit is wired in parallel connections. In the base of the street fixture an inline fuse is connected into the circuit that goes up to the fixture to protect the lamp head.
Yes, you can easily use it. Just install it as you would any other 120 volt light fixture and change the bulb from a 240 volt bulb to a 120 volt bulb. It will work just fine.
Yes 220 & 240 are considered the same.
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.
no
For a 30 amp 240 volt circuit, a wire size of 10 AWG should be used.
For a 240 volt 40 amp circuit, the appropriate wire size is typically 8 AWG (American Wire Gauge) for copper conductors.

You don't. This sounds like a strange situation. Get an electrician.
no
The terminology T8 suggests to me that the fixture is a fluorescent fixture. These types of tube fixtures need a ballast to make the tubes ignite. If you are trying to operate this type of fixture on 220 volts, you will need a ballast that requires a 240 volts input voltage source.
