Step 1. Wear safety goggles, thick gloves, and a hard hat (trust me).
Step 2. Get an Electrical license.
Step 3. 277volts AC is created from 480volts AC.
480volts AC has three hots (Brown, orange, yellow), and a green wire ground.
WIth your ELectrical meter, touch Brown to Green, or Orange to green, or Yellow to green.
Step 4. Look at your meter, if it says 277, you've got it!

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.
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.
Can you install a receptacle that is rated for 240 volts to a 277 volt line?
No, the receptacle's rating is 240 volt and that is the maximum voltage allow to be applied to that device. To prevent this condition from happening 277 volt receptacles and switches have a larger box that they fit into. The retaining screws are set apart further that a 240 volt device which makes it impossible to install a 240 volt device in a 277 volt junction box.
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 you convert a 277 volt ac unit to 230 volt?
There in no quick and inexpensive way of doing this conversion. A transformer would have to be used and this type of winding is not common. 277 volts is the wye voltage of a three phase 480 volt system.
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 wire do I connect the 277 VAC wire to?
It depends on what 277 volt device you are trying to connect.

How to wire 277 volt lighting?
A voltage of 277 is the line to neutral voltage of a 480 volt wye three phase system. L1- N, L2 - N and L3 - N will give you 277 volts. L1 to L2. L2 to L3 and L3 to L1 will give you 480 volts. Wiring of three phase equipment should be in the domain of qualified journeyman electrician or apprentices under the supervision of a qualified journeyman electrician.
Can you wire up a 240 volt single phase water heater to 277 volt single phase?
no

How do you check FCM for head light problem in dodge caravan 2002?
You need a scan tool, a wiring diagram, and a volt/ohm meter. You need to check wiring between the FCM and the headlight bulbs.
