Ikea light wiring Q

[electrodoom]

Hi everyone!

I have what I think is a really basic question but since electricity is magic for me I can't figure it out on my own.

I removed the ceiling rose and am left with the following wires:

The connection on my Ikea lamp looks like this:

My question is can I wire the 2 neutral and 2 live wires from the ceiling into the appropriate connector block and tape both earth wires with tape, since the lamp has no earth?

Please help!

no,
did you take a photo of the fitting before removing ????

i guess not

One cable will be the live & Neutral in and the other will connect to the live - go to the switch and then return the live back

you need to work out which is which wire - Live/neutral - OR switch

do you have a multimeter/voltmeter ? and know how to use it ?

Colours dont really mean much as one cable will take the live to the switch - for example say the brown and then the blue will return the live , so BLUE & BROWN cna be Live
often the blue would have a brown sleeve to denote its actually used as a Live conductor

so for example the 2 blues may go the the new light to provide a neutral and return switched live
and the browns connected together in a separate connector

Brown to brown in a connector block. Earth to Earth (bare wires) also in connector block. And the two blues to the lamp.

You should use a lighting junction box, but keeping it basic

It's a shame that whoever fitted the original rose didn't think to sleeve the "returning" switched live

...or note when disconnecting the wires.

Thanks for the advice so far. I asked my neighbour how did they do it and they said they did it the same way as my asked question. So I did the same, against the advice here, and it worked, nobody died and the house still intact.

Can anybody tell me why I shouldn't have done it that way?

Do you have a second light fitting in the room, turned on by the same switch?

Do you have a second light fitting in the room, turned on by the same switch?

Yes.

 

[RandomGrinch]

Yes.

There was an assumption made (and given the limited information given - it was understandable), that your light fitting was the only one in the room.
If that was the case, one of the cables at the light fitting would have been a supply cable, and the other would have gone to the switch - providing a switched live back to the fitting.

Instead and I may be wrong, what you appear to have, is a daisy chain of lighting cables from the same switch.
At one of your other ceiling roses, you may find some additional wiring.
A good example here:

Multiple lights from a single switch

Adding one or more extra lights so that they are all controlled from a single switch

and tape both earth wires with tape, since the lamp has no earth?

The earth wires must also be connected together in a suitable terminal block - despite this fitting not needing an earth connection, fittings further down the chain may require one. Just taping the twisted wire together isn't an acceptable way of ensuring a reliable earth connection.
