I see jingoism is alive and well on here!
I've seen excellent electrical installations both here and throughout Europe (maybe not Greece), and I've seen wiring that should be disconnected on sight in both.
I've done a lot of farm installations throughout my career, and was bringing in and using IP55 rated consumer units (fuseboxes, back then), complete with RCDs, when the nearest you could readily get in this country at the time would be open backed, wooden framed Wylex units with rewireable fuses. RCDs (if you could justify the bank loan to buy one) had to be mounted along side the fusebox, and were nearly the same size.
I could argue that continental wiring practices back then were far in advance of UK ones, and that it's only recently that we've caught up.
