[QUOTE="Geoff1946, post: 520629, member: 28452"] If your light fitting has an earth (green/yellow) you can't just abandon it. You must source an earth connection from your house wiring. Black and brown are not normal colours to find leading to a light, so it's anyones's guess. However if there was a working light there before they must be live and neutral which could be determined by testing. There is a sporting chance that it's mixed old and new standards, brown live, black neutral, but as I say guessing! It should be tested. Your real issue is the absent earth. Do not install that fitting without finding an earth. If that's too difficult you may be able to find an alternative double insulated fitting which doesn't need an earth. [/QUOTE]
