The am-meter of the load panel, indicating the sum of but two gen-erator ammeters, is not essential for a simple station, butthe recording wattmeter is essential. Each generator-panel potential plug receptacle is con-nected in multiple with one voltmeter, the other being per-manently connected to the bus-bars. Thus the potentialof the generator ready to be thrown in parallel with theother may be known. One voltmeter alone may be used ifwound differentially, one coil being permanently connectedto the bus-bars. When a generator is to be connected inmultiple with the busses, a plug is inserted in the generator-panel receptacle, the potential of the generator being thusopposed in the voltmeter to that of the bus-bars.
