Electric Jug "NPA"

Oliver J. Nilsen had an electrical manufacturing works in Collingwood. They made fuses, switchgear and also had a large porcelain works. Ceramic bodied bare-element electric jugs were in use in Australia, and New Zealand from the early 1920s and were still available until well into the 1970s. They were not used anywhere else in the world. Unlike electric kettles, while the water in the jug is being heated it is electrified by the bare element. The user is protected from electrocution because the glazed ceramic water container does not conduct electricity, unlike the water. These jugs also employed a variety of locking systems so that when the element was active the jug could not be opened and it was difficult to pour the water.
