The instrument wiring in thebus chambers is concealed in iron conduits molded in theconcrete slabs. MAIN SWITCHBOARD The main switchboard is shown in elevation in one ofthe illustrations and diagrammatically in plan on the gen-eral layout. As indicated in these, beginning at the left,there are two future and three present line panels, twofuture and three present rotary panels, two futureand three present rotary panels, two battery regulatorand two booster panels, one total load pane!, twofeeder booster panels and fifteen outgoing feeder pan-els. At the top of each line panel a voltmeter and anammeter are located. Below these are a polyphase indi-cating wattmeter, a power-factor indicator and watt-hour. RriCk Pavins Electric Ry. Journal Cleveland Power—Distributing Rack for Feeders meters on two phases. Lowest of all are the controls forthe line switches. On the rotary panels are ammeters and wattlesspower indicators. The latter show the amount of wattlesspower necessary to keep the power factor of the outgoingcurrent at unity. A circuit-breaker, an ammeter, a pair oflever switches connected in parallel and a watt-hourmeter are mounted on each rotary panel. The regu-lator panels contain a carbon-pile regulator, a rheostat andvarious control switches. The left-hand battery boosterpanel is for the motor and contains a circuit-breaker me-chanically and electrically interlocked with that on thegenerator panel. Below this are an ammeter, a four-pointmotor-starting switch and a double-throw switch for con-necting the motor either to the main power bus or to anauxiliary bus. The circuit-breaker, the ammeter, the positive line switch and a f
