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.
No. Electric companies base your electrical bill on Wattage, not Voltage or Current. While ballasts wired for 240 volt will draw less current and run a little cooler than one wired for 120 volt, it will not save you money on your electric bill.
one thousand milli volt= one volt
The lamp may not fire. Check the ballast to see if it is a multi tap. Most of the newer ballasts have variable taps for different voltages starting with 120, 208, 240, 277 and 347. This is for the convenience of the customer so as not to have many different ballasts for spares, just one that will do all. A ballast is specific to the lamp wattage.
Yes, 220 volts is in the same voltage classification as 230 volts.
12 volts is less of power than 18 volts drill
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.
Pragmatically - YES A manufacturing company I know of has been using 277 V fluorescent ballasts on 240 V service for many years, and they are working just fine.
1You could get 220-240V from using the two live ["hot"] wires rather than one live and one neutral. 2Tim, Industrial control transformers are available to get 120 volts from 277 volt systems. If you feed one of these with 120 volts to the secondary coil, it will put out 277 volt from the primary. However, these are rare and are not cheap. If you are trying to use surplus 277 volt fluorescent lights on a 120 volt system, it would be cheaper to replace the ballasts in the fixtures. Another approach would be to use an autotransformer with a 240 volt primary and a 32 volt secondary. If you feed it with 240 volt and wire it to boost +32 volts that will give you 272 volt which should run the lights. But again, you are looking at $60 - $100 for one circuit of lights. 3If you have access to three phase power..... Phase to ground on a 480v 3 phase system is 277v.
A volt is a volt is a volt.
A volt is a volt is a volt.
Electronic Ballast play a important part in the lights. So we need the device which is Ballast Tester to testing the electronic ballast performance of a fluorescent light fixture is a basic process that can be accomplished quickly once you understand the operation of the high voltage transformer. The high voltage transformer is also encased in an oil bath that reduces the heat created by the action of the transformer. A low voltage, generally 120 VAC, is transformed into a high voltage, generally in thousands of volts. There must be a continuity between the wires of the high voltage side in order for the circuit to operate correctly. Heat can damaged the internal connections of the ballast. By using a volt ohmmeter the internal circuit can be quickly checked. Not only in the voltage, but also in the current and others factors.

Not necessarily. It's the wattage of the lamps that determine how much power is used. 277V lighting merely allows for more lights to be on a circuit than if they were on a 120V. The current that is printed on the ballast, times the voltage the ballast is connected to, is what determines the cost to operate the fixture. This is the true wattage of the fixture. The wattage of the lamps are independent as new electronic ballasts can power a numerous amount of tubes of various wattages.
There are several ways to convert a 240 volt input to a 1.5 volt output. If the 240 volt input is alternating current (AC), a simple transformer can reduce the 240 volts to 1.5 volts (AC). A properly configured resistor or impedance coil in series with the input and output would also do the job but a tansformer also serves to isolate the output from the input offering greater protection for the 1.5 volt device. You If 1.5 volts direct current (DC) is required, a rectifier circuit is needed after the 1.5 volt AC output. If the source is 240 volts (DC), A resistance circuit in series can reduce the output voltage. You can also use electronic circuitry to chop of the 1.5 volts.
