You need to rewire to a lower voltage at panel or get a transformer that steps down 277 to 110 volts. Make sure wire is sized for new load as well as breaker.

Do you have a diagram for converting 277 volt light to 110 volt?
It sounds like the fixture that you acquired was from an industrial site. 277 volts is the star point voltage of a 480 three phase system. You will have to change the ballast out to the proper voltage that you need. If you want to spend some money you can get a step up auto transformer to make the conversion but the cost would off set the cost of a new fixture many times.
What size wire is required for 277 volt fluorescent lighting?
Wire size is governed by amperage not voltage. Voltage is an insulation factor when talking about wire. Add up the amperage of fixtures you want in the circuit. Once that is found then the size of the wire can be calculated.
Is there a way to install a 277V light on a 120V circuit?
no ----------------------------------------------------------------------------------- Stepdown transformer. More expensive than buying the correct light fixture. Y-THINK-Y
What wire do I connect the 277 VAC wire to?
It depends on what 277 volt device you are trying to connect.
What voltage reading would you get from a 277 480 volt system?
From a three phase four wire distribution system the voltages would be as follows. From L1 to N - 277 volts. From L2 to N - 277 volts. From L3 to N - 277 volts. From L1 to L2 - 480 volts. From L2 to L3 - 480 volts. From L3 to L1 -480 volts.
Can you use a 277 volt high pressure sodium light in my garage?
Not unless you have 277 volts in your garage. Open the fixture and check the ballast. Some of the commercial fixtures have multi tap connections for different voltages. If 120 or 240 volt tap is present then you can use the fixture.
Are all 480 Volt light fixtures 3 phase or are some single phase?
I do not believe any lighting fixtures of any voltage have ever been made to work off of three-phase circuits. Light Fixtures are always single-phase 2-wire circuits In the USA the standard voltages for branch circuits are: 120, 208, 240, 277 or 480 The light fixture must be rated to match whichever field voltage is being used. Some light fixtures are made multi-rated so they can be used on more than one circuit voltage
Can incandescent lamps be 277V?
High Intensity Discharge fixtures can use 277 input voltages. These types of fixtures have ballasts and different wattage lamps available. The fixtures are mostly used in industrial and commercial applications.
How do you hook up an old traffic light to work off a standard household outlet?
Most traffic and city street lights run on 277 volts. So chances are you cannot power the light from your house power, which is 220 or 208/110 volt.
Can you get 110 volts from 277volts?
The voltage of 277 is the wye connection of a 480 volt three phase supply. The only way to reduce 277 to 120 volts is with a step down transformer.
If you had 277-480 3phase power feed can you still use it to power IT equipment rated at 110-120V?
yes
How can 240 vOLTS power a 277 vOLT light?
Slightly dimmly
What is a 277 volt fluorescent fixture?
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.
Can you use 240V single phase power to power 277V fluorescent light fixtures?
No...but you can buy an "autotransformer" that will boost the 220 to 277. Transformers of this kind can be the auto type or isolation type and are available at a much higher cost that it would be to just buy 220 volt ballasts and sell the 277 ones at your next yard sale. The fluorescent lamps probably won't start with such a severe undervoltage (80% rated). If they do start, they won't work well and the lamps will have reduced life.

What is 7 percent of 277?
7% of 277 = 7% * 277 = 0.07 * 277 = 19.39
What is 125 percent of 277?
125% of 277 = 125% * 277 = 1.25 * 277 = 346.25
