Using a U.S. Appliance in an Asian Country

12/06/2007 1:04 AM

I have doubts and require some assistance to my query in regards of US appliance use in the Asia country. I have a washing machine and a dryer presented by a close friend in the US which operate 220 a.c. / 60 hz. I am not sure whether that it is operatable in my country. In my country the operating voltage is 50hz / 230Va.c.

I have known as a fact that they are using 110v / 60hz for most of their electrical appliances, but what is the operating supply used in the US for washing /machine, dryer, centralized heater and air conditioning. The plug top used in the washing machine is different from the ordinary household appliances and heavier equipment has the cable directly linked to the breakers. How many leads in the 220v supply and what is the configuration of the supply from the main distribution board.

Some motors are designed to operate on both 50 and 60 cycles, but not usually. If I were you, I would contact the manufacturer.

The voltage is not a concern, as all equipment designed for use in the US has a voltage tolerance of +/- 10%. With a nameplate voltage of 220, Both machines will operate anywhere in the range of 198-244V. However, there are 2 other issues which must be addressed.

  • Will the motors operate on 50 Hz?
    • There should be a nameplate directly on the motor in each machine. The motor nameplate should state whether it will run on 50 hz.For the dryer, this is usually accessed by removing the large cover from the rear of the machine. In the washer, the motor is underneath. You will have to tilt the washer back to get to the bottom & view the nameplate. (Do not lay the washer on its back. In some units the transmission gearbox is not sealed, and laying it on its back or side will allow the lubricant to leak out.) If the motor is not 50 Hz rated, you may be able to find a 50hz replacement motor locally.
    • You could try to run it on 50 Hz even if the motor nameplate does not state 50 Hz. Leave the cover off for a test run of 5 minutes or so, then feel the motor casing. If the case is not excessively hot, try a longer run. If the motor is still a reasonable temperature after 30 minutes of operation, you should be fine.
  • Does the machine require a neutral connection?
    • Most USA 220V equipment use 110V for controls, so the power connection contains a neutral wire. If the original connection is 2-wire (plus ground), you're fine. Either the controls are 220V, or there is a control transformer inside the machine. If the connection is 3-wire (plus ground), you will need to install a center-tapped isolating transformer to create the neutral connection. The center tap goes to the neutral connection on the machine, and should also be connected to a solid earth ground at the transformer.

First, please read carefully and understand fully documents that were attached your appliance.

I your close friend is right, your appliances will able be operated in your country with 50Hz-from 180~230VAC, but the motor will be little hot.

And you can use changeable socket from 2 pins to 3 hole. In this condition if there is a electric light shock, please use whole socket with grounded circuit.

I am sure your appliances are exported products or use for foreigner markets of America.
