Wiring Diagram Quemston Power House—Hydro-electric Power Commission of On volt oil circuit lncakern and disconnecting Bothhigh and low voltage breakers have rupturing capacities ofthe order of 1500 \.—considerably greater than anythingof the kind previously produced in Canada.

The 12,000 volt disconnecting switches are mechanicallyoperated. They are rated at 3,000 amperes and are so ar-ranged that the three switches forming a group operatesimultaneously. The 110,000 volt disconnecting switches areof the three insulator type, with centre insulator rotating;they are rated at fiOO amperes. The supports for the highvoltage disconnecting switches are either standard susi)ensioninsulator or 42 ific
