Rotor of a Main Generator. Following are the results of tests made of thesemachines, together with the guarantees made by themanufacturer: Guaranteed. Actual. Full load Three-quarters load One-half load Temperature rise within the 40 degree cent, limit. The Svvitchboard. The generator circuits and the outgoing trans-mission lines are controlled from the main switch-board. This is so placed on a balcony, extending intothe main bay, from the second floor, that the attend-ant may be at all times in view of the machines, andhave a general supervision of the building.
