How can I connect my thick wires into an ikea wire connector

Question

I have thick wires that can not be twisted into one hole of the wire connector, so can I split the wire into two section and feed them into the connector?

Answer 1

You can instead replace the IKEA connector with another one that will accept the thick stranded wire on one end and the wire inside the box.

Answer 2

You can use Wago 221, works with stranded and solid core, available in two sizes (normal for 0.14-4mm² and large for 0.5-6mm²), and in two different shapes:

Answer 3

Do not do this. The contacts are designed, tested and CE rated for one whole cable to go into one hole, using them differently to this will invalidate your insurance. For high current applications, you may have split unevenly and it can overheat; you can't do a tug test that it has clamped correctly on both sides; you can't guarantee there won't be stray strands that might cause a shock hazard.

Either get a suitable terminal block, or use a reducing ferrule on the stranded end that can then fit into the terminal you have. (Unless you're in the habit of putting ferrules on cables, getting the right terminal block will be cheaper as ferrules always seem to come in packets of 1000)

Answer 4

Replace the thick wire with one that has conductors of appropriate size for the connector in IKEA lamp.

Answer 5

You can also use wire nut (aka wire connector) with one thick wire and one or two thiner wires.

This type of Ikea connector prefers solid not stranded wires.

Found in many stores like wire nut

Answer 6

Cut off 1/3 to 1/2 of the strands, twist what's left, shove it into the hole, make sure there are no loose strands outside and do the tug test.

Ignore the fearmongers, the connector will be the weakest point of the whole setup and that won't change whatever coble or ferrule you use.
