There are two fuses; one is for the extractor fan (it turned off when I pulled it out) not sure about the other one.
Still not sure about putting a shaver socket in, but I do think I need to move these fuses because I want to put a false wall in front of them. Would...
I have this in by bathroom, I'm assuming its a fuse for the extractor fan. Firstly, it looks like are spaces for two fuses, does this mean there is a spare one? Secondly, could I wire a shaver socket from here?
