Contact your power provider or power company. 3 phase sometimes is not available in certain areas (mostly rural). They have to run extra wires from the power pole or grid to your place where you want 3 phase.

A three phase service can be tested for voltage. This test lets you know if the fuses or breaker has an open circuit through them. Use a voltmeter set to one scale above the working voltage of the circuit. Place the test leads from L1 to L2 and check for voltage. Next place the leads from L2 to L3 and check for voltage and finally place the leads from L3 to L1. If a voltage is read between all of the phases the service should be operational. If the service is a three phase four wire system a safer way to check for voltage is each phase line to ground or neutral should produce a voltage.
As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
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-energized.

∙ 12y agoIf the three phase service has a neutral (or 4th wire), then it can be done just by using the 4th neutral and ONE of the legs (l1-l2-l3). If there is no 4th wire that is neutral, then it cannot be done without a transformer.

∙ 12y agoThree-phase supplies are obtained from three-phase alternators.
A three-phase alternator has three separate stator windings, physically displaced from each other by 120 degrees. As the rotor spins, the field winding induces a separate voltage into each of the stator windings, with each voltage displaced from each other by 120 electrical degrees. The stator windings are then connected together internally, providing three external line conductors, A, B, and C. The potential of each line conductor is displaced from each other by 120 electrical degrees -in other words, each line conductor reaches its peak value of potential 120 electrical degrees apart and in the sequence A, B, C (called its 'phase sequence').

what is the cheapest electric supply cost single phase or 3 phase?
The cheapest service to construct is a single phase service. A three phase service requires more equipment and materials to complete a service.
Can you plug a 2 phase welder on a 3 phase plug?
No. Three phase service is something that you would need to request from your power company. You'd need to not only have service, you also need to have an electrician run 3 phase service into your home.
How many single phase can you run on a 100amp 3 phase?
You can divide a three phase service into (3) single phase circuits providing you have a 4th neutral wire.
How to Test for single phasing?
You can do that in one of three ways: 1- current on each phase, 2- phase to gnd voltage, 3- phase to phase voltage, preferably with multiple meters, the three lines has to be balanced within ~ 3%
What is the minimum voltage a 115vac 400hz 3 phase motor will run?
Yes the minimum voltage of an 115vac 400 Hz 3 phase motor will run. You can run a single phase motor on a three service but you cannot be run on a single phase.

How many wires come in from the weather head?
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.
Load test on 3 phase induction motor?
When you do a load test on a 3-phase induction motor you are checking the power factor, viz slip, and efficiency of the motor. You can test various loads with this test.
Can you plug a 2 phase welder on a 3 phase plug?
No. Three phase service is something that you would need to request from your power company. You'd need to not only have service, you also need to have an electrician run 3 phase service into your home.
How many single phase can you run on a 100amp 3 phase?
You can divide a three phase service into (3) single phase circuits providing you have a 4th neutral wire.
How can you get 3 phase connection?
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.
How can you get 240V single-phase power from a 240V 3-phase service Can you just connect to two poles of the 240V 3-phase service?
If the 240V 3-phase service is 240V phase-to-phase, then you can get 240V single-phase by simply picking two phases (poles, as used in the question) and connecting the load across them. This is simply one third of a standard delta connection. If you need 120V/240V split phase, i.e. with a neutral, as used in residential services, you will need a transformer. If the service is actually a four wire "quadraplex" service, however, you will probably already have that 120V/240V with neutral connection phase available. In this case, you will need to pick the two phases correctly in order to get the proper 120V service half.
How to Test for single phasing?
You can do that in one of three ways: 1- current on each phase, 2- phase to gnd voltage, 3- phase to phase voltage, preferably with multiple meters, the three lines has to be balanced within ~ 3%
What size service conductors for a 225 amp 3 phase service?
4/0 copper phases and neutral
What is the minimum voltage a 115vac 400hz 3 phase motor will run?
Yes the minimum voltage of an 115vac 400 Hz 3 phase motor will run. You can run a single phase motor on a three service but you cannot be run on a single phase.
Why 3 phase motor burnt when a phase missed?
You lose one third the service so the motor overheats and runs slow if at all.
