I want to install a lamp with 4 cable, namly two brown, one blue and a yellow-green cable:
Out of my wall I found 4 cable (yellow-green, blue, brown and black):
I tried to connected the lamp as follows (Left side the lamp, right side my wall):
I didn't connect the yellow-green cable because I just wanted to check if the lamp works. However with both combinations, the light didn't go on. Did I do something wrong?
