I am located in Saudi Arabia

Actually , most of the country is 220v. It is only the part where I live that has been 110v, and now they want to standardize the whole power grid. That is good IMO, but will be a rough ride for a few days/weeks.

Quote:
Here in the US power is sent to our homes as 230 volts, three phase. Our outlets are typically 115 volts, except for ones powering stoves, ovens, laundry rooms, etc. 115v is what you get when you connect only one phase to an outlet. So usually half of a homes 115 outlets are connected to one phase, and the other half are connected to the other phase. The 230 volt outlets use both phases.


This is exactly what we have in our area.

Appliance change may be a problem but not a big one. I am planning to buy a few step down 220/110v transformers for the refrigerator and freezer to use for the rest of their operational life. Most other appliances are automatic 220/110v ( like TV , laptop ... etc. ) or can be manually switched to 220v ( like washing machine ).

So, appliances can still be used for a few years after the change, it is the hickups and expected problems during the change that I am more worried about.
