Contexte

Pays: Canada
État/province: Ontario
Période: This version of panel used c. 1901/2 +. Dismantled and removed from operation c. 1963/4.
Canada: The Sault Ste. Marie Canal was converted to electrical operation in 1895, largely in an effort to maximize efficiency during cold weather when traffic through the Canal was heaviest. The contract for the electrical plant, and the installation of an electric lighting system for the canal and powerhouse was awarded to Canadian General Electric Co. of Toronto and Peterborough, Ont. When completed, the Sault Ste. Marie Canal was the first ship canal in the world to be electrically operated, and the first to be totally electrified with electric power and lighting along the entire canal. (Ref. 3, pp. 93-150)
Fonction: Originally housed the 9.5 amperes arc lighting circuit controls for the switchboard in the Sault Ste. Marie Canal powerhouse. Panel modified following conversion from d.c to a.c. system
Technique: Installed on the front right side of the powerhouse switchboard, this panel housed the 9.5 amperes 2000-volt arc lighting circuit controls. As on the other panels, this one had all meters, circuit breakers, and other controls grouped on the front, and the dangerous live wiring rear-connected to enhance safety and improve the appearance of the switchboard. Original panel configuration in 1895 was substantially different from this later, modified version. As early as 1906, the d.c. arc lighting system was converted to the a.c. system. , necessitating the installation of a new ammeter, voltmeter, and circuit breaker to the switchboard. (Ref. 3, p.134]
