Hi, in the process of fitting a new light for the landing, and have a problem. On removal of old light, live and neutral were easily identified, but have a third single core black sheathed wire that was connected to what appears to be an isolated connection on the fitting.
At first I thought it might be the earth, but two things puzzle me....1. Shouldnt it be copper? instead of a silver metal and 2. On testing it, its also live!
What should I do with this third mystery wire?....whats its purpose?...
Thank you[/img]
