Wow, that's quite a revelation! No prescribed limits on the current a given cable can carry? Here in England we always look upon Sweden as being a very safety-conscious country, so this is really surprising.
It doesn't even mention cable types. But you still have to meet the general requirement that cables should not be a fire hazard or risk injury to people or livestock.
There is in fact a Swedish standard for ampacity, which is recommended in the regs. (I don't recall the number, but it is of little interest here anyhow) I have been meaning to write and ask if one can use the IEE or DIN standard instead.
So I could wire a house in Sweden with British, French, or Swiss receptacles and it would be code compliant?
Presumably, yes. I have been thinking of using Swiss or French sockets, since they have a "cleaner" look than the Schuko sockets.
However, you cannot use the British ring main. Two conductors in parallell have to follow the same path. And you cannot use British T&E, since the earth must not be downsized.
The current plans seem to be to remove the present mandatory regs altogether and convert them into a standard, like the BS 7671 in England. Thereafter, I presume one will be allowed to wire to the regs of one's own choice, including the NEC and the IEE.
Yes, Sweden has a good record of safety. However, electricity has been and still is an exception. Ungrounded sockets were the norm in residential wiring up until 1994. In fact, it was illegal to sell grounded products for household use prior to the EU entry.
Still, there has been much resistance to grounding as it is seen as both unnecessary and a safety hazard. One lady even sued her landlord one or two years ago over the grounded sockets landlord had installed. The court ruled in the landlord's favour, though.
