You don't. A ballast with a 347 volt input is a commercial ballast. The 347 volts comes from a 600 volt three phase four wire Y system. You can change the ballast out to a 120 volt and rewire the unit but in most cases it is cheaper to buy a completely new lighting fixture.
No, not a good idea. You have to use a 347 volt ballast.
NO! a 120-277 electronic ballast requires one "hot" wire and a neutral from either a 110V or 277V supply. If you supply it with two "hot" wires from a 208 V supply, it will instantly burn up.Yes. A ballast with a specification range of 120 volt to 277 volt will work on 208 volt. These ballast use intelligent voltage sensing technology and it does not matter if the source is a hot and neutral or two (2) hots. Don't believe it? Call a ballast manufacturer instead of giving incorrect answers.
If your light bulb voltage rating is under 300 volts then yes it can use 300 volt wire. The voltage rating of the wire is the maximum voltage that the wire can safely carry. The three common insulation groups is 300 volts, 600 volts and 1000 volts.
The first thing we have to do is clarify the question. A cable rating of 125 volts is an insulation rating of the wire. Like wire with ratings of 300 volts, 600 volts and 1000 volts these are the highest allowable voltages that can be applied. A wire that is rated for 300 volts is good for 120 volts, 240 volts and 277 volts. At test research facilities, equipment is tested to destruction. The label that is given to wire as a result of the tests is the highest safest voltages that can be applied to that particular wire. So when you see a wire that has a label stating that it is rated for 300 volts it means that any voltage under and up to 300 volts is safe to apply. So to answer the question yes, the 125 volt insulation rating on the cable can be used to supply a source of 120 volts to a 120 volt rated piece of equipment.
On your model number the figures after 400MH are the voltages for that ballast. A 40 represents 240 volts, 12 represents 120 volts and yours 48 represents 480 volts. Looks like this is a industrial fixture and not meant for residential use.
No, not a good idea. You have to use a 347 volt ballast.
Yes, but it will not work.
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.
Operating at half the required voltage, the lamp will not operate at full capacity if it comes on at all.
A 277 volt lighting fixture is one that is usually used in an industrial application. The reason for this is the voltage rating. A voltage potential of 277 volts is the voltage to neutral (ground) of a three phase four wire 480 volt distribution system. 480 volts / 1.73 = 277 volts. Rather than having to add a transformer to the system to provide 120 volts for lighting, manufactures produced a ballast for fluorescent fixtures that operates on the 227 volt potential.
wire it in series
no
Sounds like both phase wires are connected to the same phase.

The 300 volt insulation rating on wire is the maximum amount of voltage that can be applied to that wire. If your range falls within that range then it is safe to use. Some commercial ranges use 480 and 575 volts. For theses types of ranges the 300 volt wire will not do, it will have to be wire with a conductor whose insulation rating is 600 volts or greater.
