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 .
Can a 277 unit heater be supplied with 240 volts?
No, a 277-volt heater cannot be safely operated with a 240-volt power supply. Matching the correct voltage is essential for the safe operation of electrical devices. Using a lower voltage than the device is rated for can lead to insufficient performance and potential damage.
Can you install a 277 volt receptacle in place of a 240 volt receptacle?
No. To prevent this sort of thing from happening, the 277 volt device and receptacle is physically larger that a 240 volt receptacle and will not fit in a regular receptacle junction box. For a 277 volt system the proper size junction boxes have to be purchased.
What is the benefits of using 277 volt electrical equipment?
with 3 phase lighting you do not have to use as large of wire and can use one neutral for every 3 current carrying conductors so it cut down on material costs ( as voltage increases current decreases) <<>> The voltage 277 is the star-point voltage of a 480 volt three phase system. By using a 480 volt wye system you have the dual ability of running 480 volt three phase equipment along with 277 volt lighting. The side advantage is the ability of using the phase voltage to ground (neutral) 480 / 1.73 = 277 volts for general lighting of the building the 480 volt equipment is located in.
How do you wire a 277 volt heater from 480 volt box?
Answer for USA, Canada and countries running a 60 Hertz supply service.The 277 volt heater can be wired to a single pole breaker in a 3 phase 4 wire 480 volt distribution panel. The breaker should be sized to the amperage draw of the heater. 277 volts is the star point (wye) voltage of a 480 3 phase system. 480 / 1.73 = 277 volts. The third answer is not correct, two phase legs of a 480 volt system will give you 480 volts. It is the phase leg to ground (neutral) that gives you the 277 volts.A 277 Volt heater or device may not be wired to a 480 Volt circuit or box. A 277 Volt device may only be wired to a circuit rated for 277V/480V equipment.2 legs of 480 volts will give you 277. But since you don't know the answer you probably shouldn't be doing it! Please don't kill yourself, hire a licensed electrician.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-energizedIF YOU ARE NOT REALLY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
Can you run single phase 230 from one side of 480 volt 3 phase?
No, you will not obtain 230 volts. From a wye connected three phase 480 volt supply, 277 volts can be obtained from one phase leg and the neutral on the wye connection. 480 volts/1.73 (sq. root of 3) = 277 volts.
Wiring diagram to convert a 3 phase 480 volt generator to 277 volt?
You should not need a wiring diagram. If the generator has a star point (wye) connection then the phase voltage to ground (star point) is 277 volts. 480/1.73 = 277.
In a normal 277 volt situation is there one hot leg or two?
277 volt systems aren't normail systems
Can you wire a 240 volt window ac from a 277 volt feed?
no

What yields a higher heat output a 2kw 277 volt electric heater or a 5 kw 230 volt electric heater'?
2kw = 6,827 Btu/ Hr 5kw = 17,076 Btu/Hr 5kw yields 10,249 Btu more /Hr

What wire do I connect the 277 VAC wire to?
It depends on what 277 volt device you are trying to connect.
Can you wire up a 240 volt single phase water heater to 277 volt single phase?
no
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.
