Context

Country: Canada
State/Province: Unknown
Period: late 19th century
Canada: An example of a wood cleat 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: Cleats were used to support and conceal exposed wiring in indoor work.
Technical: An example of a wood cleat. 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.
