I have two ceiling rose lights in my corridor, I have managed to replace one without the need of any wiring connector. I achieved this because it had one Live, one neutral and one earth connector. So all I did was connect L and N to the new LED light and cover the earth wire with some tape. The new LED doesn't require earth
However, I have now realised the other ceiling rose has several wires(a search suggested that this is due that being the main one)
I did some search and found that when it comes to converting these type of wires, you need connectors (wago connectors) I don't understand the purpose of these, are these connectors really necessary? Can't the wires that can't be used, just be taped?
I'm based in the UK
The first ceiling rose that I converted by taping the earth wire(this picture show the setup was)
The following is the picture of the other ceiling rose, which I found to have too many wires on
UPDATE
This is the photo of all the wires after being removed from the ceiling rose setup.
Marked in Yellow: 4 earth wires, connected in pairs - I'm thinking of putting this in a wire connectors of five
Marked in blue/purple: 5 wires connected to a 3 slot section(Neutral). these were connected in pairs of two black together, two(one blue and black together) and one blue that goes to the actual light - I'm thinking of connecting them to a wire connector of 5
Marked in green: connected to a 3 slots sections(Loop), all three were red wires were connected separately - I'm thinking of connecting them to a wire connector of three
Marked in red: three wires connected to a section of two(Live), one pair(consisting of a red wire and green/yellowish) and one red wire coming from the light - I'm thinking of connecting these to a three slots wire connector.
Do you think the setup I'm going for is correct?
