They are also connected to the citymains, so that if the supply of feed-water falls below a prede-termined amount the connections to the city mains are auto-matically opened, thus preventing any likelihood of shortage. For supplying water under pressure to the step bearings ofthe turbines there are three steam-driven pumps. As a precau- and so arranged as to permit the operator to face the mainengine room when controlling the main machines. The instrument board has the following panels in use: Five13,200-volt generating panels; three exciter panels; three alter-nating rotary panels; three direct-current rotary panels; three13,200-volt outgoing feeder panels; one direct-current booster
