Dorman Smith made one in which the fuse WAS the live pin. One end of the fuse had a threaded portion that screwed into the body of the plug.
Wylex had an alternative design with the fuse contained within the body of the plug. This only had a round earth pin. The live and neutral pins were flat pins, similar to the pins on Wylex fuse holders for consumer units.
The firm where I served my time used DS plugs & sockets in the workshops
AncientMariner:
Can you still get the fuses?
WIth this plug being about the size of a 2amp 3 pin plug, it must have been a bit tight connecting on to the end of a flex for a 240v 2 or 3 kW electric fire?
Finally, in "Teach Yourself Building", did J E MacFarlane refer to plugs, or plugtops?
