In Sweden GFCI's are required by law to protect the whole wiring (since the first of July 2000) in all new constructed residential houses, schools, day-cares, temporary installations and things like that. Before that (since 1996) it was required in new constructed/renovated bathrooms, Garages, to protect electrical heating in floors, new installed sockets placed outside. Even sockets placed inside which could be used to feed electrical machines outside (lawn-mowers and such) should be protected. Many people however chooses to install GFCI’s in their “old houses” just to be on the safe side even if it’s not required by the code.
