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
-
By 1896 all receptacle fuses had suffered from the defect that they had some exposed metal and were not safe to handle when alive. This problem was likely realized years before because in 1893 a patent for an insulated handle was issued. There were also a number of designs on the market before 1900 by Dorman-Smith Ltd., which were a great advance over much contemporary practice but which do not appear to have been patented. One of these was the "factory damper", which, although it had been in production for a number of years before the Home Office Regulations of 1908 were introduced, was found to comply with these stringent requirements and its manufacture was continued unaltered for many more years. - Area Notes
