(2,916amperes) being possible without injurious sparking. Theguaranteed efficiencies of the 400-kilowatt dynamo are: 93per cent, at 25 per cent, overload, per cent, at full load, per cent, at three-quarters load. per cent, at half loadand 89 per cent, at one-quarter load. The general electrical distribution system is a two-wiresystem operating at 240 volts, but in addition to this there isalso a four-wire multiple voltage system for use in obtaining tapped off of any one of the three machines, or off of either twoof them combined, giving with a main voltage six availablevoltages, ranging as follows: 40 volts. 80 volts. 1
