Yes. But if you don't know the answer to the question please hire a professional. The life you save may be your own.

What is the minimum volt rating of wire used in a 3 phase 4160 volt phase to phase system?
5000 volt
Can you use a 240 volt 3 phase disconnect with 460 volt?
It's possible, but not at all economic. Usually the 240V (sure it's not 277?) has been stepped down from 480V service already. Sounds like this is a commercial application. 480 is rare in residential, but quite common in commercial. If you need 480, you'll need to get ahead of the step down transformer.AnswerYou cannot obtain a three-phase supply from a single-phase supply.
What is the Largest amperage single phase 120 volt breaker made?
6000amps <<>> The above answer must have big lugs to accommodate 6000 amp capacity wire. In my breaker catalogue the largest 120 volt single pole breaker is 70 amps, 277 volt single pole is 150 amps and 347 volt single pole is 100 amps. The 120 volt single pole breaker occupies two opposed slots because of its length.
You are measuring 480 volt from phase to phase and 280 volt phase to ground but one leg measures 440 volt phase to ground why?
Check for a blown fuse in one of the phase legs.
Can a 230 volt single phase watt hour meter be used to monitor 115 volt single phase?
Yes it would work pretty well but it might not meet its accuracy specification.

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 .

What is the difference between single pole and double pole thermostats?
A line thermostat on a 240 volt heater must open both of the supply lines that feed the heater. This is where the double pole thermostat is used. On 120 volt heaters only one hot line needs to be opened to shut the supply off from the source therefore a single pole thermostat is used.

Can a 3 pole100 amp600 volt disconnect be used in a 3 phase 250 volt application?
Yes - Most switches have two positions for the fuses. The bottom of the bracket for the fuse holders can be moved up to accommodate the shorter 250V fuses.
What is dpst switch?
Double pole Single Throw switches are sometimes called DPST switches. Assuming the circuit is single phase two wire system, DPST - are used to isolate the ciruit. Isoloation occurs on both terminals hence it is called double pole. This isolation occurs at only one end in the circuit, hence it is called single throw.

Check for a blown fuse in one of the phase legs.
Can you use a 2 pole breaker for a 120 volt single phase circuit?
A single phase circuit uses a 2 pole breaker if the circuit is 120/240 split phase and the load is connected 240. Both legs are hot, so both need to be protected. This is the normal US/Canada configuration.
Panel box with a 3 pole 4 wire 440 volts 3 phase electric and you need to pull 220 volt single phase with 2 pole 3 wires how do you do it?
Open a discuss question page, more information is needed as to what you are trying to do.
Can you use a double pole thermostat to replace a single pole thermostat?
Answer for USA, Canada and countries running a 60 Hz supply service.A double pole thermostat is a line thermostat and not to be confused with a low voltage stat. When the heating load has 240 volts for a supply voltage, both lines from the distribution panel are supposed to disconnect when the thermostat reaches the set point temperature. A single pole thermostat is only used on a 120 volt heater an the return leg from the heater is a neutral wire.A two pole thermostat can be used on a 120 volt circuit but a single pole thermostat should not be used on a 240 volt circuit. The reason being is that on a 240 volt circuit using a single pole thermostat, one "hot" leg doesn't get isolated from the heater and is always "hot" to ground. This is a shock hazard if you are working on the heater and depending on the thermostat as a disconnect from the distribution voltage.Before you do any work yourself,on electrical circuits, equipment or appliancesalways 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.
