Service voltages for lighting

THE General Electric Company's annual analysis of population reported as being served at various lighting voltages shows a continued shift toward 120 volts, with decreases in both the 115- and the 110-volt percentages. The percentage of population receiving lighting service at 125 and 130 volts is almost negligible (actually less than one-tenth of one per cent) and shows no sign of increasing. The trend is as shown in the following table.
