Edison\u2019s pioneering 1882 Pearl Street station transmitted direct current at 110 volts, and the same voltage was used when alternating current at 60 hertz took over in American homes. Later the standard was raised a bit to 120 V, and in order to accommodate heavy-duty appliances and electric heating, North American homes can also access 240 V. In contrast, in 1899 Berliner Elektrizit\u00e4ts-Werke was the first European utility to switch to 220 V and this led eventually to the continent-wide norm of 230 V.<\/p>\n

Japan has the lowest voltage (100 V) and the dubious distinction of operating on two frequencies. This, too, is a legacy from the earliest days of electrification, when Tokyo\u2019s utility bought German 50-Hz generators and Osaka, 500 kilometers to the east, imported American 60-Hz machines. Eastern Honshu and Hokkaido island operate at 50 Hz. The rest of the country, to the west, is at 60 Hz, and the capacity of four frequency-converter stations allows only a limited exchange between the two systems.<\/p>\n
