Hey guys,
I'm replacing a smoke alarm that was removed some time ago but not encountered 3 core and earth because I don't touch a graet deal of wiring.
Obviously the smoke alarms are on the lighting circuit but I'm not sure how to proceed because of this third yellow wire. The bare copper wire has no earth sheath on it and the yellow wire has not been stripped back so I am puzzled about which will be the earth and whether the remaining wire is completely redundant?
Any help much appreciated!! Fitting a smoke alarm shouldn't be this difficult, I would have opted for the battery alternative had the wiring not been hanging out the ceiling..
