I learnt the other day that I had gotten the Swedish phase order backwards. [Linked Image]

'Old' cables L1/2/3=black/brown/black with white stripe but newer cables had L1/2/3=white/brown/black. I - and probably a lot of people - simply assumed that the colours had the same meaning in all cables. I have no idea why they did like this: The 3 and 4 wire cables were identical.

This is the problem with being the only member from a country. There's nobody to tell you "No, stupid, it's like this..."
