I live in Japan where we have a paltry 100V. In our apartment it's made by for by having lots of (20A) circuits - 3 for the (small) kitchen alone [which uses gas for the stove anyway]. Total of 14 breakers for a small 3 bedroom + living + kitchen apartment.

In 3 years we've only tripped a breaker once - running a microwave, toaster oven and dishwasher all off the same outlet at once.
