Ballast connection diagrams are on the identification label that is on the ballast.
Your ballast should show two wires for supply side of ballast. Make sure that neither side of this is grounded to the light and connect the 220 V from your breaker to these two wires and then connect a ground to the chassis of the light from the panel.
A higher wattage HPS bulb may work with a ballast that is rated for a lower wattage bulb , but may appear to be dim and will not produce the rated light output. It is best to match ballast and bulb accordingly.
The way a metal halide light is set up, there's a transformer in it called a "ballast." The ballast powers the bulb. You can wire ballasts to a lot of different voltages--which voltages you can use are dependent on the ballast in question--but 120v single phase is almost always one of the choices. So yes, you can do it.
When you buy the bulb. All of those specifications should be on the package. To figure the Kilowatts it's pulling and cost to run. kW = amps x volts / 1000. then just take your kW x price per kw. and that will give you how much it costs to run that bulb for one hour. The amperage is on the label of the ballast. When you connect the ballast to power you will see it along with the voltage and pf of the ballast. F40T12 twin 8 foot tubes, ballast usually draws about .75 amps.
A T8 LED tube has to be used with a ballast to bring the correct voltage to the tube for it to operate correctly. Removing the ballast from the circuit will prevent the tube from operating.
Connect them in parallel. The black wire from the ballast to the black line wire. The white wire from the ballast to the line neutral. Connect the ground wire to the ground screw which is located in the body of the fixture. Grounding of the fixtures is essential.
Your ballast should show two wires for supply side of ballast. Make sure that neither side of this is grounded to the light and connect the 220 V from your breaker to these two wires and then connect a ground to the chassis of the light from the panel.
If the 250 watt bulb is a HID or similar type the ballast comes complete with the fixture. The bulb socket is also part of the fixture and comes pre-wired to the socket. To connect the bulb to the fixture all that has to be done is just screw it into the fixture's socket.

It sounds like you are talking about a two tube eight foot fluorescent fixture. Open the fixture up and you will find a ballast that has probably two yellow wires, two blue wires, two red wires and a black and white wire coming out of it. The 120 volt supply will connect to the black and white wires that protrude out of the ballast. Black ballast to black supply and white ballast to white supply.
A higher wattage HPS bulb may work with a ballast that is rated for a lower wattage bulb , but may appear to be dim and will not produce the rated light output. It is best to match ballast and bulb accordingly.
A ballast that smells burnt is going bad. The ballast will have to be replaced to fix the problem.

A good sentence for the word ballast is.......The ballast is not heavy enough and the boat is about to sink.
