I'm not really sure I like the Austrian system where normal people aren't allowed to do anything beyond replacing a light bulb but licensed electrician are not checked upon at all unless there is a fire or someone is electrocuted.
Much the same in Australia, although to my knowledge a homeowner has never got into trouble for doing their own wiring. There has been some jumping up and down by some in the trade to ban the sale of fittings to the general public. They regurgitate the same old story of people wiring up power points with bell wire as justification.
Rather, there should be some education as how to do things correctly instead of keeping wiring standards and practices as part of some kind of secret society.
Prohibiting sale of wiring accessories will simply cause people to be more creative; and not necessarily in a safe way. Not to mention the black market and sale of second hand fittings.
