The oil switches, storagebatteries, station light and power transformers, andmain generator field rheostat are located on the bal-cony. The rheostat is placed near the front of thebalcony in order to be in view of the operator. The switch cells and switches are arranged inthree sections of five circuits each designated as the.

On the main floor behind the switchboard at theend of each switch section is a terminal board.
