Sweden: See Austria. You are allowed to replace switches, sockets and the like. The electricians union of course claim that only electricians should do this, at $50/h [Linked Image]

Having said this, D-I-Y work is common and there is a shortage of electricians. This means that much small scale commercial wiring is done by laymen. (Connecting power for alarm systems, emergency lights and other add-ons to old buildings. I've seen really scary "sparky-killers" that have looked like neat wiring.)

Electricians consider us engineers to be the worst D-I-Y'ers, and rightly so. (A friend had wired up a fuse box outdoors (!) with old reused single insulated wires tied to nails on the wall (!). He used the fuses as light switches...)
