I have bought a new ceiling light for my wifes latest project, an Art Deco living room ! On removing the existing fitting I found that there are only two cables both of which are coloured red!
As the new fitting has a step down transformer I assume it will be necessary to wire it correctly i.e. Live to live and neutral to neutral and somehow fit an earth (the two red cables are contained in an iron tube conduit).
How do I find out which is live and which is neutral without any test equipment??
