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 following is the picture of the other ceiling rose, which I found to have too many wires on
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?
