Period: 1930s+
Canada: An example of a fuse cutout of a type used in Canada. Part of a large and varied collection of over 7500 electrical items acquired and documented by Ontario Hydro in the1960s. The collection was thought to be the largest and most comprehensive of its kind in Canada and was donated to the National Museum of Science and Technology in 1992.
Function: An electrical device which interrupts the flow of electrical current through a piece of apparatus or equipment.
Technical: An example of a fuse cutout. In the period 1890-1899, fusing was often done using fuse wire in an open porcelain cutout with a cover of sheet mica or porcelain. In the latter part of this period, the cartridge fuse was introduced. It was most common in industrial settings but was the only type that could be used when the current was more than 30 amps (Ref. 2).
