Two sets of wires for lighting

Post by n9ne980 »

Hi,
So Im currently switching out my lighting from and found that there are two sets of cables coming out which doesn't match my new terminal block.
Do i just place both wires in each designated place?
I've attached some photos for clarification

That wiring suggests you have 2 lights or a light and fan on the same switch

One thought from neelix's post ***Other than this ceiling light do you have a wall light that has an integral pull cord switch?***

As you are removing the rose to put this pendant up you will need to replicate the wire connections, you May be lucky and can securely and safely feed the
2x neut wires (blue) from ceiling into your neutral terminal in the light pendant
Then feed the 2x live (brown) wires from ceiling into the live terminal block in the light pendantthen feed the 2x earth (yellow/green) from the ceiling into the earth terminal of the light pendant.
If however thterminal block is not big enough to accommodate those without any lwire core (the copper bit) being exposed then you will need to replicate the terminal block setup in the ceiling rose for the live and neutral, the best way to do this is using 2x 3 way wago connectors (which will replace the terminal blocks in the rose currently installed)
Each terminal on a wago takes a single wire
Feed 2x neutral wires from ceiling into 2x terminals of the 3 way terminal wago
Feed 2x live from ceiling into 2 terminals of the other wago.
You would then
remove the live wire from the terminal block in the light pendant and feed that into the 3rd terminal of the live wire wago
Remove the neutral wire from the terminal block in the light pendant and feed that into the 3rd terminal of the neutral wire wago.
Keep the 3 terminal block in the light pendant and connect the 2x earth wires from the ceiling into the middle terminal (earth) of the terminal block in the pendant (as this is earthing the lihlghtimg pendant)
Both earth wires from lighting circ into the earth terminal

For the live and neutral wires you do not want any of the copper core visible. The wires must be pushed into the wado sufficiently so there is no copper core exposed.

Idealy tou would put the wagos into a wago box and push this up into the ceiling and use another bit of live and neutral wire from the 3rd wago terminal going into the terminal block of the pendant but I don't think you have space for this and you would need to source a small bit of compatibal and matching electrical cable to do this.

Thanks for the responses,
Yes I have two lights in my room wired to one switch.
I'll try your suggestion, I think there is enough room to accommodate X2 wires!

:thumbright: goes without saying electric off first at the cons unit making sure on one turns it back on while you're working. and make sure you terminate correctly so no cores are exposed (as they are in your 1st pic on the live and neutral) if there is too much copper core exposed so you can't terminate without a little hanging out trim the core down a little.

Much appreciated! I'll make note of trimming down the core, seems the previous electrician didn't do a decent job!
