I have a standard UKbathroom shaver socket (2x2 pins for 230v and 115v) which I am trying to locatea fuse for. The fuse box is located in a side wall and awkward to access but itsays ‘Protector’ 30mA on it. I have tried a 30mA fuse but this was too small(20mm length) as is a standard 13A fuse. I’ve also tried a 100mA fuse but thiswas too long (30mm). Measuring the cavity for the fuse from the outside it isc28mm but I can find fuses this length.

Any suggestions? I have photos but I'm not sure I can attach them.
Many thanks,
Shane
