The voltage should be between 220 and 240 VAC.

Solis 365 royal hair vac I was wondering if it was possible to use this product in australia due to the voltage difference and if there is a product made to suit australian voltage or if an adaptor...


There are products called Step Up transformers/Step Down (Voltage Converters) that can be used. We use these For our 220VAC Australian manufactured lasers when we need to run them in a Dr.'s office that only has US 110VAC.

Info from a website:
Electrical voltage in USA is 110 voltwhereas; the voltage in most of the foreign countries is 220V to 240 volt. A voltage converter / transformer, also known as power converter are usedto convert electricity coming out of the wall to match the voltage of yourdevice. These Voltage transformers or converters can be used safely withRefrigerators, Microwaves, Juicers, Blenders, Coffee makers, Power Tools,Stereo Systems, TV's, Video Games, DVDs, Hair dryers, Chargers, computersand other electronics when travelling abroad..

Remember to leave at least a 100-percent margin for power surges/spikewhen buying a transformer. Some items, such as Televisions, computermonitors spike when you turn them on. For these products you need to buy avoltage converter transformer that is at least 3 times the items capacity.Power tools, laser printers and heating appliances like coffee makers,toasters, microwaves, Halogen, Fluorescent bulbs you must leave a marginof 3-4 times.

Voltage transformers are made to convert single phase 110 or 220 volt.American 220 Volt consists of 2 phase of 110 Volt and European 220 Voltconsists of 1 phase of 220 volt.

Volts x Amps = Watts (i.e. 110V x 0.5 AMPS = 55W). Please make sure not torun any appliance with higher wattage then voltage transformer's wattage.This might damage both: your appliance and the transformer!

I hope this helps.

I have 110 volts n each leg but not 220 across both why??


In a traditional North American residential electrical panel (120/240 volt, single phase), installing a single width or single pole circuit breaker, you would expect to read 120 volts from the breaker terminal screw to either ground or neutral. A double width or double pole breaker would provide 120 volts from either of the breaker terminal screws to ground or neutral AND it will provide 240 volts BETWEEN the TWO breaker terminals.

A single-width circuit breaker case that contains two handles is NOT a two pole circuit breaker (these are called "tandem" or "1/2 size" breakers). This is because a single width breaker engages only one "line" in the panel. A double width breaker will engage 2 "lines" as a triple width breaker would engage 3 "lines" of a 3 phase panel. A single wide breaker can not physically engage more than 1 "line" so it will never be able to pass 240 volts.

You must install a double width / double pole breaker to safely supply a 240 volt circuit / device.

Wiring schematic for MTB217 cooper b line


I would suggest taking a closer look at the motor name plate. I am not familiar with a 120/240 three phase service. When I checked the web it shows: Voltage 115/230 (that is single phase), Max Amps 115 Volts = 19.2 Max Amps 230 Volts = 9.6 , Single Speed, Square Flange, RPM = 3450, Threaded Shaft, Frame = 48Y Used on the following models: Sta-Rite Max-E-Glas, Max-E-Glas II, Dura-Glas, Dura-Glas II, Dyna-Glas, Dyna-Max Pentair Whisperflow, Pinnacle and Anthony AR2 Series. You should also show what voltage you are connected to.

Single phase motor 220 convert to110v; do you have switch wire inside the motor


There should be a label showing the change, one wire gets switched over to a different screw, all motors are different, but all basically the same, some will not switch. It would be just as easy to run a new line to your motor and it will be right, single circuit, 220 volt,?amp, no worries., Your motor as is will not run in 110 volt mode at all. Hope this helps.

I got a single phase capacitor motor is is 22-11 amps it keeps triping my bracker one to two min of running now my bracker is fifteen amp do i need to get a higher amp bracker?


You need to determine the following: what else is on that circuit? You might have a 15 am circuit but you need to calculate what else is running. Please clarify... is it 22 amps at 120 volt and 11 amps at 220 volt? The motor will draw more amps when starting and reduce while it is running. Do not just toss in a larger breaker, that cold potentially lead to a fire or damage to your equipment.

Bosch universal mixer 800W. How do I change a 110 volt to a 220 volt? Is it possible?


Bosch is not very good about putting manuals or other documentation online for older products, so I'll have to give you generic advice.

Some electric motors have optional voltage connections. If your motor has this feature, there will be a box or removable plate on the motor with 110 Volt and 220 Volt connections inside. You would need to replace the line cord with a 220 Volt cord having the correct plug for the location you plan to use the mixer, and connect the motor "hot" wire to the 220 V connection in the motor junction box instead of the 110 V connection (the neutral wire goes to the same neutral).

If there is no such option available on the motor, you would also have to replace the motor with a 220 Volt version. Check the labeling on the speed control (inside the mixer) to be sure it is rated for 240 VAC, and check the power label by the power cord. If the label gives a single range of input voltages spanning both 110 VAC and 220 VAC (e.g., "Input 97 V- 265 V") then you only need to change the plug. Unless the electrical parts are all rated for 240 VAC or higher, conversion is not safe.

Some products (especially desktop computers) have a recessed switch on the back that lets you select either 115 VAC or 230 VAC input power. If you have this on the mixer, all you have to do is use a small tool to push it to the other position.

An alternative is to get a 230 VAC - 115 VAC transformer or inverter rated for at least 800 Volt-Amps and wire it with a 230 Volt plug on the primary side and a 115 Volt socket on the secondary side; then you can just plug in your unmodified mixer to this. If you cannot find a box like this, you can buy a "control transformer" from an industrial equipment supplier and put it in a suitable metal box. I recommend including a power switch and a 4 Amp dual-element fuse or breaker on the primary side circuit; you don't want somebody burning up the transformer with a 1200 Watt microwave oven or griddle.

I have a WESTINGHOUSE WELDER type rs 250 that is wired for 440 volt and need to change to 220 volt.


HI:) If that is a 3 phase 440 volt and you want it to use 220 volt 1 Phase you will have to get a phase inverter to change it from a 3 phase to a single phase.

What amp is the plug?


This is a 220 unit and it must be plugged into a proper 220 volt plugin.
