> we license nothing or we just pick somewhere to draw it My original comment was because in the UK most of this stuff isn't licensed* - even installing a gas stove doesn't need a license, which I'd argue is a lot easier to screw up than a light switch. There are 'regulations' on how things should be done, but these are merely guidelines in most cases - you won't have any issues with the authorities when trying to sell your house or with insurers if it's not up to scratch. It would be interesting to see how accidents caused by this compare in the UK and US. On the other hand two things we do strictly regulate are 'listed' buildings and the removal of trees in your garden. *I think the same is true for most of Europe.
