120 277V means that the electrical system is designed to handle both 120 volts and 277 volts. This is common in commercial and industrial settings where different voltage levels may be required for various equipment and lighting fixtures. It allows for flexibility in power supply options.
What else can I help you with?
How can you attach a 120 v Light Fixture to a 277 v system do I need a ballast so what kinda of ballast?
To attach a 120V light fixture to a 277V system, you will need a step-down transformer with a 277V primary and 120V secondary. This will allow you to safely power the light fixture at the correct voltage. You do not need a ballast in this case, as ballasts are typically used with fluorescent lights and not for altering voltage levels.
Where does 277v power used in America?
It is used in Industrial lighting.
Are 277V lights wired the same as 120V?
The connection diagram is the same, one hot-leg and one neutral. But if you do not have 277 volts as your source voltage, connecting a 277 volt light (usually a ballast) to 120 volt will not work. Conversely, if you hook up a 120 volt light or appliance to 277 volts, it will quickly become toast.
How do you convert 277v to 120v for an outlet?
i think you just have to change the breaker from a 277 to a 120. 277 breakers are usually a 2 pole breaker and 120 is a single pole breaker. NO. 277v is not two poles, it is one pole, one single pole breaker in a 480 volt 3 phase system (typically). If you want 120 volts from a 277 volt source you need a step down transformer 277 volt to 120 volt , or 480/277 to 120/208 .
Wiring diagram for 277 v ballast?
A wiring diagram for a 277V ballast typically involves connecting the incoming 277V power supply to the ballast, and then connecting the ballast to the light fixture. Make sure to follow the specific wiring instructions provided by the manufacturer of the ballast to ensure proper installation and to maintain safety standards. If unsure, it's recommended to consult a professional electrician.

What is the difference in amps used by lighting wired 277v vs 208v?
Answer for USA, Canada and countries running a 60 Hz supply service.Assuming you are using the same fixture, and assuming the fixture can operate on either voltage, you will get fewer amps with 208v than with 277v. However, a fixture designed for 208v will probably burn up on 277v, and a fixture designed for 277v will probably not produce any light on 208v.The two fixtures in reality are quite different. The 277v fixture is using one leg and neutral of a 277/480v 3 phase 4 wire system and the 208v fixture is using 2 legs of a 120/208v 3 phase 4 wire system.In commercial and industrial installations the 277v fixture is most common.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.

Arithmetic mean = 120
How many volts in 3 phase?
It starts out with 480 Volts, which is used to power motors. 480 can be stepped down to 120/208/277. The 120 operates normal appliances, while 208 can be used for dryers and welders rated for 208. 277V is usually used for lighting circuits. 3-Phase is used in commercial and industrial settings.

Is there a way to install a 277V light on a 120V circuit?

Can you connect a 277V ballast to 208V line service?
No. A 277 volt ballast needs the correct voltage to operate. The 277 voltage is derived from the star point voltage of a 480 volt three phase system (277/480). The 208 voltage is a three phase line voltage whose star-point voltage is 120 volts (120/208).
