The 12,000 to 100 volt potential transformers with protective fuses andresistances were ordered in March, 1921, from the Canadian General ElectricCompany. Practically all these instrument transformers have been delivered. Switchboards Switchboards for controlling the units have been laid out and material forfive main units purchased. Control switches and indicating lamps for oil cir-cuit-breakers, rheostats and governor motors are Type ordered in 1922 HYDRO-ELECTRIC POWER COMMISSION 193.
