I am going to finally connect my lamps today. In the past, it was simple for me as, they already had connection boxes with the previous lamps already conncetd, and I only had to exchange the wires. Now I have live wires hanging out of my ceiling. What do I need minimum to buy, and how do I conncect the lamps to the wires. I know that in Germany Live wires are Brown, Neutral are Blue, and Ground are Green/Yellow. Some old house may have L-Black, N- Gray, G-Red. So, is there are prefered order or which wires I should connect first? I plan on purchasing the little patic boxes where you can connect all of the wires together. Where does one buy these? So I connect Live to Neutral, after connecting Ground to Ground? I also have a three way switch?? Two switches in different locations, for one lamp. Do I connect two lives to two Neutrals? Or is it simply one live to one neutral , a switch router to a switch router, and a ground to a ground? There are too many wires!!! And finally, are thes plastic boxes safe? Should I also wrap them up with electrical tape?
