LIGHTING AND POWER CIRCUITSThe general lighting of the main buildings and also of thecoal siding and the approach road is carried out by fortyOritfamme arc lainps. The lighting installation also in-cludes about 200 incandescent lamps. The feeder cablesfrom the 650-volt a. c. auxiliary switchboard and from thed. c. switchboards are three-core and single cables, respec-tively, rubber insulated, lead covered and armoured withsteel wire. For the branch circuits rubber insulated and. PARK ROYAL—MAIN ENGINES FROM SWITCHBOARD GALLERY FROM NORTH BAY braided cable is used, drawn into heavy gage simplex steelconduit. With the exception of the offices, water-tight fit-tings have been used throughout. SUB-STATIONS The Royal Oak sub-station is equipped with four 400-kwtraction motor converter sets, worked in parallel with abattery having a i-hour discharge rate of 1680 amps, inconjunction with reversible boosters. All the motor con-verters were specially manufactured for this plant by BrucePeebles & Company, of Edinburgh. The sub-station alsocontains two 200-kw motor converters for d. c. lighting andpower purposes.
