I had been having some trouble with vaious equipment tripping the main fuse. For example a Dyson hoover + 1000 Watt kettle, or kettle + iron.

It has been bugging me for a while so I checked the fuse box and found that while the fuse box for all the plug sockets is marked 15 amps / 240 volts, the fuse that is in there is only a 5 amp / 240 volt fuse.

This seems to be the source of the problem, but why would the landlord/hauswart have put in 5 amp fuse? Will I cause any problems by going and buying a new 15 amp fuse? Maybe this is a Swiss thing to stop us using too much electricity...
