ELECTRICAL INSTALLATION. _Main generating sets._--There were four engines and dynamos, each having a capacity of 400 kilowatts at 100 volts and consisting of a vertical three-crank compound-forced lubrication inclosed engine of sufficient power to drive the electrical plant. The engines were direct-coupled to their respective dynamos. These four main sets were situated in a separate water-tight compartment about 63 feet long by 24 feet high, adjoining the after end of the turbine room at the level of the inner bottom. Steam to the electric engines was supplied from two separate lengths of steam pipes, connecting on the port side to the five single-ended boilers in compartment No. 1 and two in compartment No. 2, and on the starboard side to the auxiliary steam pipe which derived steam from the five single-ended boilers in No. 1 compartment, two in No. 2, and two in No. 4. By connections at the engine room forward bulkhead steam could be taken from any boiler in the ship. _Auxiliary generating sets._--In addition to the four main generating sets, there were two 30-kilowatt engines and dynamos situated on a platform in the turbine engine room casing on saloon deck level, 20 feet above the water line. They were the same general type as the main sets. These auxiliary emergency sets were connected to the boilers by means of a separate steam pipe running along the working passage above E deck, with branches from three boiler rooms, Nos. 2, 3, and 5, so that should the main sets be temporarily out of action the auxiliary sets could provide current for such lights and power appliances as would be required in the event of emergency. _Electric lighting._--The total number of incandescent lights was 10,000, ranging from 16 to 100 candlepower, the majority being of Tantallum type, except in the cargo spaces and for the portable fittings, where carbon lamps were provided. Special dimming lamps of small amount of light were provided in the first-class rooms. _Electric heating and power and mechanical ventilation._--Altogether 562 electric heaters and 153 electric motors were installed throughout the vessel, including six 50-hundredweight and two 30-hundredweight cranes, four 3-ton cargo winches, and four 15-hundredweight boat winches. There were also four electric passenger lifts, three forward of the first-class main entrance and one in the second-class forward entrance, each to carry 12 persons. _Telephones._--Loud speaking telephones of navy pattern were fitted for communication between the following: Wheelhouse on the navigating bridge and the forecastle. Wheelhouse on the navigating bridge and the lookout station on the crow's nest. Wheelhouse on the navigating bridge and the engine room. Wheelhouse on the navigating bridge and the poop. Chief engineer's cabin and the engine room. Engine room and Nos. 1, 2, 3, 4, 5, and 6 stokeholds.
