Adaptor to connect a 2 pin shaver plug to a BS1363 flat pin socket.
The two pin shaver plug has two round pins, and should comply with BS 4573. This adaptor is not marked with any standard, but is most likely of the correct dimensions.
This adaptor is marked 'RAZOR ADAPTOR ' and 'FUSED'.
Neutral (bottom left as viewed from the inside) is connected directly to the lower socket hole.
Line connects to the top socket hole via a 5A fuse - probably the wrong value. 1A would be more usual.
The fuse is necessary, as the circuit this would most likely be connected to would have a 30A fuse - far too large for the slender wires typically used on electric razors.
Empire, No. 6025.
The adaptor is also marked '13A 250V' but this only refers to the pins - the shaver plug this would be used with is not rated to 13A.
