How do you obtain a 230 volts single phase supply from a 400 volts three phase four wire supply?
You can use a transformer to step down the voltage from 400 volts three phase to 230 volts single phase. Connect one of the phases and the neutral of the three phase supply to the transformer primary winding and then connect the secondary winding to get the desired 230 volts single phase supply.
How is electrical energy delivered to the end users?
End users generally subscribe to an electrical service according to their power needs. A residential home, for instance, might have a three-wire, 220-volt, single-phase service rated at between 60 and 200 amps, to a service panel supplying 110-volt and 220-volt branch circuits. A commercial end-user may need three-phase 277/480-volt system supplied on 4 wires, rated for 800 amps overhead or more underground.
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 many watt generator to run a 150 amp service?
You will need a 50 kW generator for a single phase 120/240 volt service.
Can you use 240 volt 3 phase to run a machine that is 240 volt single phase?
No, 240 volt 3 phase power cannot run a machine designed for 240 volt single phase power. The electrical requirements and connections for single phase and three phase systems are different, so using the wrong type of power can damage the machine and pose a safety risk. It is important to match the machine's power requirements with the correct type of power supply.
What color is in a 480 volt three phase service?
brown blue yallow
Can you replace 240 volt service with 480 volt service?
240 volt service is residential, split single phase. 480 volt service is commercial/industrial, three phase. In theory, with the approval of your municipality and electric utility, you could replace split single phase with commercial three phase service. However, the equipment for the replacement (transformers, feeder wire) would likely not be provided by the electric utility and would have to be bought by you. This equipment cost usually makes any benefit of such equipment not cost effective. Not to mention the cost doesn't end there. Your building electrical system would have to be rebuilt as a three phase system. That is like apples and oranges. You wouldn't even be able to plug in a typical 120v load without connecting transformers to step down the voltage.
What is the minimum volt rating of wire used in a 3 phase 4160 volt phase to phase system?
5000 volt
How can you get a 240V single-phase power from a 120V 3-phase service?
First of all there is no common three phase 120 volt service. There is in North America a three wire 120/240 volt single phase service. That being said, if you want to change a 120 volt source to 240 volts it must be done with a transformer. Its classification is a step up transformer. The primary side of the transformer H1 - H2 will be connected to the 120 volts. The secondary side of the transformer X1 - X2 will be connected to the 240 volt load. The transformer is sized by the current required by the 240 volt load.
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 you wire up a 240 volt single phase water heater to 277 volt single phase?
no
In a 240 volt single phase circuit A phase is 4000 watts B phase is 7000 watts what is the neutral load?
Question is incorrect. in a 240 Volt single phase circuit, how can you have A phase and B phase?

How do you get a 380 volt 3 phase motor to run on a 220 volt 3 phase power source?
Use a transformer.
How do you change a 3 phase 440 volt motor to a 3 phase 220 volt motor?
You can not change it. 440 volt is by design. However you run it with 220 single phase supply, but it would run far lower power.
