Context

Country: Canada
State/Province: Unknown
Period: 1930s+
Canada: An example of a fuse 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: A safety device which protects lamps and other electrical devices from over-voltage.
Technical: Edison produced the first replaceable type fuse plug which screwed into sockets. These early fuses were porcelain which made it difficult to identify a blown fuse. Many different identifiers were tried in the 1920s and 1930s (such as this fuse) before G.E. introduced the type of fuse now used in domestic settings - the Pyrex plugged fuse plug (Ref. 2).
