Context

Country: Canada
State/Province: Unknown
Period: Unknown
Canada: An example of a ceiling rosette 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 wiring device used to provide a means of connecting electrical wires coming from the wiring system of a building into a single wire or cable wire; cleat rosettes were used specifically to support and conceal exposed wiring in indoor work.
Technical: An example of a porcelain ceiling rosette of the cleat type. During the late 1880s, the wood cleat was replaced by the porcelain cleat and the solid porcelain insulator gradually gave way to the two-piece clamping style (like this one). In June 1913, Ontario Hydro wiring rules prohibited the use of wood moulding to cover conductors and limited the use of metal moulding to circuits of less than 1320 watts (Refs. 2-4).
