I was looking at the wiring that was left by the installer to get my head around how this would work but confused myself even more so I was looking for someone to explain it to me.
There are two 10w LED downloads in a bathroom, controlled by a switch outside. They are wired in the loft into a junction box. From there the cable comes down to the switch outside, but the cable they have run is a 3core plus earth. Which is were I was puzzled, if this is three cores, how can you then switch the light of the mirror on and off separately?
Surely you would need to run two cables?
