Canada

An example of a receptacle of a type used in Canada. Part of a large & varied collection of over 7500 electrical items acquired & documented by Ontario Hydro in the 1960s. The collection was thought to be the largest & most comprehensive of its kind in Canada & was donated to the National Museum of Science & Technology in 1992.

Function

An electrical wiring device used to provide a point at which power can be drawn from a wiring system by means of a plug .

Technical

An example of a receptacle of the early 1920s. In the early 1890s Charles G. Perkins of Hartford, CT, patented a electrical ceiling fixture & a plug & receptacle for electrical purposes was patented in 1894, incidentally introducing the nomenclature. During the 1890s several inventions made household current available. The most common approach was to utilize the existing Edison socket with its familiar screw base (Ref. 4). A simple arrangement which did not require the service of a mechanic to change a lamp was a necessity for commercial production of electric lamp sockets & receptacles. In 1880 Edison introduced the screw cap which still bears his name (Ref. 3).
