Second reason not to use this method is construction of todays computers, where "switch" is just a signal key that tells motherboard to turn power supply on. So there is no real separation of electric power (110 VAC) like it
230 V~ 50Hz
Where do they have 110 V~ ???
[clipped more] Torroid Corp. has a (somewhat) simplified chart of voltages: http://www.toroid.com/custom_transformers/technical_bulletin_2.htm http://www.powerstream.com/cv.htm lists Country Voltages and Plug Styles. http://users.pandora.be/worldstandards/electricity.htm is a more graphical/map presentation. Wikipedia history is good reading (if more than wanted). http://en.wikipedia.org/wiki/Electricity_distribution North American centric with worldwide comparisons. Single and three phase stuff even. It is difficult to find out about the many years of generating systems inching upward from 105V, through 110V, past 115V and now firmly at 120-volts. Seldom does anyone say plainly to the consumer that a 120-volt standard allows for losses inside a building, so that 115-volt equipment is meant to be used on 120-volt systems. Mostly 110 is a memory artifact from bygone years.
