Hi all
Now, I never touch electrics (that's what professions sparks are for) but I'll replace 'like for like' if it invlolves unscrewing a terminal. So...
This weekend I was up in the loft adding some top up insulation, and lifting the cables as I did so I managed to disconnect some wires from the low voltage transformer for the bathroom downlights. When I looked at the transformer I could see that it was cracked / damaged so I replaced it 'like for like' and connected everything back up as it was - I have working lights!
So, when I look at the way it's wired it's like this - from the pull switch I have a live (red sheath) and earth (unsheathed) in the same cable and the live wire is connected to the transformer (as the instructions say no earth is required), but the neutral (black sheath) appears to run in a separate cable and it looks to me as though the neutral wire has been cut and both ends connected to the transformer. I'm guessing that the correct way to do this would be to use a junction box for the neutral wire? Is this correct? I'm getting a spark in to have a look soon but just wanted to put my mind at rest as I thought lighting circuits were always twin and earth (1.5mm).
Thanks guys
