In addition to the live steam and exhaust piping and the and receivers, the engine room basement also containsthe electric cables to and from the switchboard. These are placedoverhead along the east wall of the building. Turner oil filtersand pumps for forcing the oil to the engines are also in the engineroom basement. For feeding cylinder oil an oil pump, made by passes through the upper of the two Thomson wattmeters and thatfrom the fourth unit through the lower one. On the feeder boardan extra or emergency panel has been provided; it is the one imme-diately over the wattmeter panel of the lower board. An auxiliarybus bar (the upper one in Fig. 15) connects all the feeder panels,including the emergency one; the regular feeder panels have twosingle throw switches, one for connecting to the station bus andone fo
