   never seen a plug with a fuse like this in north america before — pretty neat. it is on an ikea light. sliding cover to access the fuse can’t be opened when it’s plugged in.

     @dfraser but in the states you have fuses in the distribution boxes, don't you? so why put fuses in a light?

     @kaia i think it’s there to protect the wire and lamp socket, which might not be able to handle the full current from the wall… maybe they got away with extra-thin wire while still having electrical safety approval

     @kaia @dfraser

     a correctly sized plug top fuse protects from fires being caused if the flexible cable is damaged and short circuited as it will open long before the circuit breaker in the distribution board does (which could be 15 or 20A in USA)

     The UK has them because we use an unusual ring final circuit which generally has a 32A circuit breaker; so a short circuited cable could get *very* hot without the plug top fuses
