Not saying it is correct, but if you measure from the first part of the metal, diagonally to the edge of the plug base, how far is that? With 8.5mm of insulation and 4.3mm horizontally, technically it is 9.5mm from pin metal to edge of plug.
There are a lot of devices without fuses at the plug - all of the wall wart power supplies as a start - does having a fully wired integral cable and plug remove the requirement for an in-plug fuse? My reading is that it does not but how do the others get approval?
