Re: Another unusual plug and some other questions
GEC were certainly making plugs with DP cartridge fusing before then, with two or three pins and 5 or 15A gauge. Cartridges were offered as 1, 2 or 5A IIRC. Other manufacturers were probably doing the same.
Prior to these there was a plug with internal rewireable fuse, I cannot recall the maker or whether it was a product on general sale or just a concept piece.
