I think on average European circuits tend to have fewer outlets on them than the equivalent North American one, and yes, I think 16amp is about the largest circuit found in most of Europe. The UK of uses 32amp circuits and as a result, our outlets are still all screw terminal [grub screw type rather than wrap around]. Slightly sideways thread drift, I _far_ prefer the wraparound screw terminals on US/Canadian devices to the British style tunnel terminals.
