The pilotlamps h, h are also connected to the same lines, so that theywill indicate when the machine is up to voltage. The upperterminals of the voltmeter receptacle are connected to thevoltmeter V, so that by inserting the plug, the voltmetermay be connected to either dynamo.

Fig. 57. § 17 ELECTRIC LIGHTING. 55 Between the generator and feeder panels, the shunt S forthe main ammeter M is inserted, so that the total currentsupplied by the two machines must pass through the shunt,and the ammeter M thus indicates the total current method of connecting the bus-bars to the feedersdepends to some extent on whether the feeders are to passout at the top of the board or whether they are to be carrieddown through the floor. In this case, they are shown con-nected to the bottom terminals of the switches and carrieddownwards. One side of each feeder switch is connecteddirectly to the — bus-bar; the other side connects to the-(-bus-bar through the circuit-breaker g. Lamps k and / maybe connected directly across the bus-bars, or, if desired, theymay be made to indicate when a circuit-breaker is out byconnecting to the outgoing terminals of the feeder k is shown connected in t
