Here in Brazil we live with dual voltages, 220 in the north and 110 in the south. Everyone uses a 220 / 110 converter for their computers and monitors and any 110 volt accessories. The power is supplied from the wall with just two wires, no third ground, which makes things very difficult. For the serious computer users, we have a "isolador", that creates a proper ground, and depending on the power plug of the converter, 3 or 2 prong type, it is the first device plugged into the wall. Must business that use computers will spend the extra money to run a dedicated 110 line with a 3rd wire ground in each office. I get lots of shocks working on computers here because of the corrosive nature of our environment (1km from the beach), either the computer power supply or the converter will work but shock you when you touch the computer cabinet with a wet finger (sweat). Miraculously, it doesn't seem to affect the operation of the computer, I am usually there to correct a software or virus problem and upgrade memory. I stick in my diagnostic CD or floppy and get it! It scares you at first as you are not expecting this! If it is the converter's fault, I just change the computer voltage selection to 220 and surprise the client, he doesn't need the converter, and everyone is happy! Static discharge here is very uncommon, nobody uses carpeting, just ceramic tile and cement.
