Black probably live and white probably neutral. Yellow/Green probably earth.
But you can’t be sure until you measure.
Don’t mess with electricity when you don’t have the knowledge.
My guess is:
Blue is neutral
Yellow, white, black is the three phases
Red and green/yellow is ground
but always measure with multimeter before
I like how the yellow is isolated. Red plugg, tape and a rubberband(?)
These are clearly of older standards from maybe 60s or so (not sure exact when). At that time they used “tändtråd” (not sure how to translate it) of all the colorful colors.
Often (but not a rule:) red was the old standard for earth. Now it is red/green. This is why it was twisted together in same cap.
But at old installations the rules about colors were a bit iffy/loose, so the norm is to measure.
Technically you aren’t allowed to do this type of work.
I know many go “I can do this myself” (in particular if just replacing same to same, such as a broken switch or outlet) but if you don’t know anything, you should NOT do it. Please call electrician, just as many here have suggested.
Please just put everyting back in place and call an electrician before you hurt yourself // an electrician
If you don’t know the answer you shouldn’t be doing it. Besides, it is also against the law…
Lick them to find out
Red/green yellow=earth
As this seems to be an older house I’m almost certain that white or black is neutral and the other is line.
You have a mix of several colour scheme standards there, think before you act.
The *current standard* says that *line* is Brown, Black and Gray. Gray can be white, according to the same standard. Brown can be Red, according to an older version of the same standard.
Blue is *Neutral* and Green/Yellow is *Protective Earth*.
According to yet another old standard, Red was once designated *PEN*, Protective Earth and Neutral combined.
Another standard says that White+Black can be line+PEN. But it’s exact use varies a bit, and I have encountered both black and white neutral in installations. Black is supposed to be line, I think.
Yellow is almost certainly *ignitor*, the line between a switch and a light. Ignitor can also be Green. Do not confuse solid Green and solid Yellow with the alternating Green/Yellow that is designated PE. In newer installations, ignitor is often Orange.
That said,
This is what you *should* have in front of you,
– the Yellow is an ignitor. Follow it to a switch or a light. It carries a line when the switch is closed.
– Red is *probably* Protective Earth, Neutrals supposedly more reliable big brother, that helps a faulty current bypass the Earth Fault Protector so that it triggers faster on a fault. This is *not* your neutral* line.
– Blue *should* be neutral. But it’s not connected to anything. (was it once connected to White?)
– Black is *likely* your line.
Notice how there are some question marks in my answer? If you don’t know what you are doing, go fetch your favourite electrician and have him (or her) establish if I guessed right or wrong.
As said, it seems to be a buildings from the 50s or 60s,
Some Wired where added later,
the red is connected to green/yellow = ground=/ Earth.
The rest should be sorted out by a professional electrican.
IF plumbing goes wrong, you get wet,
if electricity goes wrong you die instantly…
Den är bakom den andra, sen är den andra brevid den

Measuring is knowing. If this was my house I’d have a sparky replace the wiring according to the latest norms though.
Lol electrician here i dont think u should be doing that
Connect the wires and u will find out lol xD / jk dont do it
Shit asså fattar inte varför folk är så totalt handfallna när de gäller sånt här. Hur deprimerande som helst ju. Nåt sätt lär man sig, idag har vi internet, svaret va “inte en fucking aning eftersom att standarderna e rätt wonky, skaffa en mätare o kolla”
Hur lätt som helst o så har man lärt sig hur man använder en elmätare oxå o så har man ett vettigt verktyg som man kanske behöver nån gång.
“Reglerna” av vad som får o inte får göras är ju jätte hittepå ändå av vad man läser på Elverket. Enda upp till 16 A IAF.
I think blue is neutral. Atleast in my house blue is neutral. White was older color for Neutral. So in old houses different colors can be used for neutral depending on the age of the cables.
And green/yellow is ground
Brown is L1 phase 1.
For that one i think black is line and white is neutral. Its a bit of new and old colors but since there is only one blue id say that isnt neutral in this case.
But as everyone else is saying, please leave it and call an electrician. The risks are not worth it
Thanks so much, everyone! I am set on calling an electrician. What is the best way to do that, and to help with price bargaining, what can I expect the job to cost? I am not only new to Sweden but also new to calling an electrician (if that wasn’t obvious)!
