That's why power limiters are sometimes used in Sweden. They act like intelligent main fuses. If the current draw is too large (e.g. kettle and vaccum cleaner used at the same time) it shuts of some non-critical load, typically the water heater and the electric heating. (Electric heating is very common here)
