I had a bulb light outlet, and I decided to convert it to power outlet. Now when I took the bulb light off, I discovered that there is only two wires in the wall, brown and yellow green, so I assume it's "line" and "ground"... no neutral. Now when I connected it to power outlet, it didn't work... until I took the yellow-green wire and connected it to where the neutral wire is supposed to go, and now the outlet started to work... I was able to connect electric appliances to it.
So... is it normal that use "ground" wire as "neutral"? Is it dangerous?
I'm in Europe. Thank you.
