I'm trying to replace the hanging light below and I've gotten a little confused. Shouldn't the brown wire on the left be connected to the live (red) wires rather than the neutral? I understand that the black wires on the right are connected to the blue wire, both are neutral so that makes sense. The same goes for the earth wires. I just can't understand why it is wired in this way and how it even works?!?! Can someone clarify this for me?
