sfeLOWs that •ttiis estimate checks closely with the size units in operation in Tillages of approximately the same size. Engine; Due to the fact that an oil engine has practically no overload capacity it is necessary to drive the 30 K.W. generator with at least a 50 HJ>. engine so that the maximom load which the generator could carry will not exceed the maximum output of the engine. Ho effort was made to draw hard and fast specifications covering the engine, it having been considered advisable to allow the engine manufacturers to use their judge- ment recommending the details of this part of the equipment. The engine and generator specifications weredrawn as follows: SENEBATOR. The direct current generator to be furnished under these specifications is to be rated as follows; 1 - 30 K.W. 125-«50 volt, 3^ire direct current generator with proper sized pulley, sliding base and rheostat, speed not to exceed 1300 RJ>.M. The generator is to be of the interpole type, and must be capably of operating successfully in conjunction with oil engine. Rating ; The generator shall be capable of operating continuously for 24 hours at its rated full load with the rise in temperature of the coils not exceeding 40 degrees centigrade above the surrounding atmosphere and of the eonnrutator 4^. After carrying full load for 24 hours, the generator must be capable of carrying an overload of 2Sfo for two hours without temperature rise of more than 55 degrees centigrade on the coils or 60 degrees on the conmutator above a room atmosphere of 25 degrees centigrade. Temperatures are to be measured by a thermometer in accord- ance with the rules of the American Institute of Electrical Engineers.
