Converting from three phase to single phase

Hi Bill
I may be wrong here......
But I've been around Electricity for a long time.
Have Never seen a device that does phase conversion.
A Building site or home will either have Three Phase or Single Phase Power Available
BUT...A portable (Hired) generator could be "three phase" and you could use any one of those phases individually or all three phases.

I have 3 Phase supply to my house!
But I use 230 volt Single Phase for appliances.
My Bore Pump uses a 3 Phase Motor,
(so with a voltmeter it would read about 440 vAC to the pump motor).
Some Further Info:
A GENERATOR is basically a motor used the opposite way. Rotate a motor and it Generates.
The Phases refer to the THREE Windings in the supplying generator in your suburb.
A Large Magnet passes each winding in sequence giving you the three ripples in the supply.
Our houses can choose to have 1 Phase or Three Phases from the street when you set up your electric supply.
So... to confirm, look at the wires on the supply poles to the premises. Usually three in our area (Oz)
Most people are not aware that a car Alternator is actually three phase. The Rotor is the magnet that rotates.
The only difference with an Alternator is that each "Phase" is connected to 2 Diodes (6 total) to convert the three phase to DC to charge the vehicle.
The Regulator controls the voltage to the Rotor, thereby controlling the output.
So.... An Alternator could in theory supply 3 Phase in a mobile generator. Custom Made. Constant speed would determine the frequency of 50Hz or 60Hz.
Not sure what country you are in

Hope this Helps or gives you food for thought!


Three phase electric power

Sounds like this maybe a three phase unit and you are powering it off on single phase power. Most can be converted to single phase but will draw three times the current and requires some wiring changes. It needs to be on a three section breaker for 3 phase.

Sounds like you may have a 3 phase fryer, or it is wired wrong. If you only have single phase power, it might be able to be rewired so that all three heaters are on the two main leads, this is often done at the power relay with a strap. Note the current will be much higher this way.

Hi there.
You can download Wells F67 electric fryer at http://www.wells-bloomfield.com, it contains conversion of wiring from single phase to three phase, just click the owner's manual on Service and Support page.

Hi there!
You can find conversion manual at www.wellsbloomfield.com.

If you feed single phase into the line terminals, you will get only 1/3 the heat wattage. To get all heating elements working on single ph, you'll have to separate the common ends of the elements, then connect all 3 in parallel. Keep in mind, doing so will raise your line amperage x3 also. That may put you over the contactor's max rating. Another thing, the contactor will activate on only one sequence of single phase. You may need to move the line to another 2 of the 3 connections.

Hi,
Yes but it would not be economical to do it...it would cost more then sending it back for the correct phasing...to many things to convert and change...they may however be able to send you the proper heating elements and safetys, so that you can convert it...would depend on if the proper elements still fit in the same spaces provided...I would call the company and see what they want to do...

I have a service manual for the 1600 and 1800 Broaster and it has wiring diagrams in it

You will need a rotary converter for this, or a single phase motor. A three phase motor absolutely cannot be made to run on single phase otherwise.
