∙ 12y agoPresuming that you would like the least expensive installation, the following is calculated on overhead aluminum wire. The wire size needed to hold the voltage drop to 3% would be 3/0 MCM. If the installation could be run on 240 volts then the wire size can be reduced to #2.

Yes, there is a difference between single phase and three phase circuits.
working of single phase preventor
Single phase inherently requires less equipment (it's cheaper). Three phase motors are more efficient than single phase.
None what so ever. The cost of changing all of your equipment and new service would be high. The electrical bill is based on wattage used be it single phase or three phase.
The cheapest service to construct is a single phase service. A three phase service requires more equipment and materials to complete a service.
You can divide a three phase service into (3) single phase circuits providing you have a 4th neutral wire.
There is no need of single phase to three phase conversions. Both service types are available from the local utility company.
If single phase - 2 wire service > two wires If single phase - 3 wire service > three wires If three phase - 3 wire service > three wires If three phase - 4 wire service > four wires US residential service is usually single phase 3 wire service: Two hots and neutral.
Only if you are grounded and provide a return path for the current to travel.
Most standard residential service is single phase. Therefore, I would say most all residential A/C units are single phase.
If you have single phase now, you have two options. One, is to install a three phase service or Two, install a roto phase device.
If the single line is compared to another single line and the voltage that you need is correct then you are looking as a singly phase supply. The electrical classification of single phase is that any two legs of a three phase supply can be called single phase. Look on the nameplate of the distribution panel. There it will state what the panel is, either single phase or three phase. Look at where the distribution enters the building from the utility supply. If there are three insulated conductors (red, black and blue) wrapped around a bare aluminium messenger wire it is a three phase wye connection service. If you see two black insulated conductors wrapped around a bare aluminium messenger it is a single phase service.
Bolivia uses the same as electricity service standards as countries in Europe: 230 volts 50 Hz single phase alternating current. Home appliances are fitted with Europlugs Types A and C.
The common household electrical service is usually rated as a single phase service. In North America there are a few 120/208 three phase services being put into larger homes.
You need to match the UPS to the service. If it is three phase you need a three phase UPS, and vice versa for single phase. It isn't a case of being better, it is a situation where you need to match your application.
The only benefit is you don't have to pay for a three phase service for just one motor.
