Switchboard and Exciter Set, North Pacific Lumber Company. Power Equipment of a Modern Sawmill First Large Plant in British Columbia to be Operated Throughout by Electricity—An Object Lesson for the Progressive Manufacturers that is being Taken Note by Many The widespread interest shown in the application of electric power to sawmills makes timely a description of the power equipment of the North Pacific Lumber Company's new mill at Barnet, The general arrangement is to drive the main part of the mill direct- ly from one high speed Goldie Corliss engine of 1,000 capacity, the outlying groups being driven by induction motors, current for which is supplied by one Allis-Chalmers-Bullock, 600-kilowatt, 3-phase, 60-cycle, 2,200-volt generator, direct connected to a high speed compound Goldie Corliss engine. Both of the above mentioned engines are equipped with steam operated dash pots on valve gear, and are run condensing. The speed of these engines is considerably higher than that of the ordinary Corliss engine, as the piston speed is 750 feet per minute. In addition to the above equipment the engine room contains one Allis-Chalmers-Bullock, , 125-volt direct current generator, di- rect connected to a high speed Ideal engine, which supplies the current used for lighting the mill, yards, offices, etc., for motors used in the machine shop and filing rooms, for driving of power house ventilating fans, and for exciting the fields of the large alternator. The 4-panel switchboard, built by Allis-Chalmers-Bullock, , is of neat and attractive design. It is made of blue Vermont marble, highly polished, and is mounted on a steel framework. The panels, looking from left to right, as shown in the illustration, control (1) all of the direct current lighting and motor circuits;
