I'm sure this isn't what you want to hear, but you probably need to ask an electrician familiar with your service and what you want to connect.

As a general answer, you can connect a 240v line to line resistive load like an electric water heater to any 240v source. If you also need the 240v to have 120v line to neutral, like a 240v electric stove that contains a 120v clock and oven light, then its possible if the 3 phase power is connected in a "high delta" configuration, and you connect to the correct leads. If you have a high delta service and want to ignore the 3-phase power service and wire most or all of the loads in the building as a single phase load, the utility may have to be consulted.

What are standard speeds of single phase motors?

Single Phase motorRPM (Revolution Per Minute) depends on Frequency used & the number of poles of motor.So this RPM of single phase motor usually 300 to 3000 depending upon F & P.


How can I connect a single-phase - 2 hot wires plus ground- 220V load to a 3-pole 220V breaker?

Common usage of a three pole breaker is for use on a three phase distribution panel. Single phase distribution panels only use two pole breakers for a 240 volt load.Remember that the breaker must protect the conductors that connect to the load. If you want to try and use a three pole breaker in a single phase panel just because you have the breaker, this is not a good idea even if it will fit.Purchase the proper single phase two pole breaker to match the wire size and the amperage of the connected 240 volt load. Keep in mind that connected 240 volt motor loads have to be sized to 250% of the motor's full load amperage.By doing what you want to do and a fault occurs from this type of installation your insurance company might not cover the damage that it would cause.If the distribution panel is three phase then just connect the two load wires to any two of the three poles on the breaker.


How 3 phase motors Speed is paired to number poles?

Directly propotional


What is the maximum RPM does a 3 phase motor run at?

The formula for RPM is ; RPM = Hz x (120 (constant)) divided by the # of poles. Number of poles a motor has; # of poles = Hz x (120 (constant)) / RPM.


What is two phase?

In what context? Typically people want to know this because someone referred to a residential service as 'two phase', meaning there are two hot wires and a neutral. Technically, there is no such thing as two phase power. Commercial sites are often wired in three phase power, and residences are actually using a special type of single phase power called 'Split single phase'. This has to do with the way the voltage for the hot leads is created. Residential step-down transformers on the ground or on poles use a transformer with a center tapped secondary, making each hot wire about 120 volts. The center tap point becomes the neutral wire. A phase to phase measurement gives you about 240 volts. This is technically created with only one phase from the power generation point, as opposed to commercial services which actually use all three phases. A phase to phase measurement in a commercial service yields 208 volts instead of 240.AnswerA two-phase system is very rare these days, as it pre-dated three-phase systems. It consisted of a generator with two phase windings, physically displaced by an angle of 90 degrees, giving two phase voltages displaced by 90 electrical degrees. The resulting line voltage is 1.414 times the phase voltage. A two-phase system should not be confused with the split-phase system used for North American residential supplies.

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.

Can you connect a 2 pole load to 2 single pole breakers?

Yes, but the handles should be linked together so if only one breaker trips (phase to ground short) it will kill both poles of the circuit.

Why single phase series motors have large number of poles?

All motors have a set number of poles for the speed they are designed to run at. 3600 rpm are 2 pole,1800 rpm are 4 pole, 1200 rpm are 6 pole, ect.


Where can I find the wiring diagrams to wire single phase to a 3 phase 4 wire supply?

It doesn't work that way. Phase angle relationship will affect the motor and grounding will be a problem.Another opinionThis question is not at all crystal clear to understand and what you can do will depend on where you live and what incoming electric power services you already have.If you're asking this question to find out how to produce a new 3 phase 4 wire supply from a single phase incoming service line - because, say, you don't already have a 3-phase service coming into your home or workshop and you wish to use a piece of machinery you have just bought that has a 3 phase motor in it - it can be done using an electronic phase inverter.The prices of such phase inverters go up steeply according to how much 3 phase power they have to deliver so, if, say, you have bought some equipment that has a very large 3 phase motor, it may be worth asking your electricity service utility company how much it would cost to install a new 3 phase service at your home or workshop?But, as already stated, this question is hard to understand as written, so if you are asking it because you already have an incoming 3 phase service at your main breaker panel - i.e. there are already 3 incoming service lines plus a ground wire - then in most cases you will already have available to you at least one single phase service and will have standard single phase outlets ready to use!Always, of course, depending on exactly where you live in the world, most electricity utility companies nowadays generate and distribute their power as 3 phase and then use small 3 phase delta-to-star transformers (also known as delta-to-wye transformers) in sub-stations on the ground - or mounted up high on service poles above the ground - to deliver local single phase services with a neutral to homes, offices, etc. which don't need a 3 phase service.Yet Another OpinionTo obtain a single-phase supply from a three-phase, four-wire, system, you simply connect the load either (a) between any two line conductors, or (b) between any line conductor and the neutral conductor -depending on the level of voltage required. In the UK, for example: the nominal line-to-line (line voltage) is 400 V, while the line-to-neutral (phase voltage) is 230 V.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.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
