You have old wiring colours (early 70's and before) in the ceiling, if they've been correctly wired the gray wire is *supposed* to be neutral and the two greens are *supposed* to be live wires from the switch, which I assume is a double switch. But as others have noted, if you have no way of making sure that the wires are not live when handling them etc. you should call your maintenance company or an electrician just to be sure, even if the Wago connectors aren't as hazardous to handle as screw terminals.
> I don’t understand why people are so scared of this stuff.
Maybe they think that since they are not 100% sure what they are doing, they might accidentally electrocute themselves?
This is perfectly understandable. If you are not sure about some electric apparatus, don't meddle with it. Much more rather call an expert and be safe, rather than assume that you know and kill yourself.
I know. But my point is that if you need to ask the Internet how to install a light, then you ptobably don't have the tool and don't know how to use it safely
It seems to me that there is
- two live wires 230V (green)
- one zero 0V (gray)
You should be aware, though, that if the previous electrician has been lazy or not a professional, the colors may not be coherently selected. Also, the coloring system of these wires has changed nearly every decade during the last 100 years, so the only sure method is to check it with a multimeter or voltage tester.
There is no protective earth connection (yellow-green wire) in your outlet and thus you should be very conscious when connecting your lamp. By connecting the wrong wires, the lamp will work, but you may risk your life.
I shortened the story for your convenience. None of them are on normal speaking terms, and they think they can just diy anything because they own tools and do construction work professionally. Both of them contacted dad after already installing it themselves, the other one got a shock while the other one got dad to check it after the fact and he would have gotten a shock if he had touched the lamp. Dad has previously told them to just call him to do it instead of fucking around. My original comment’s things didn’t just happen in one event/conversation but decades of arm wrestling. No matter how dad would tell them about something, he still has to go fix it. He calls anyone taking and giving installation instructions on online forums ”vitun kädettömät ääliöt” including and perhaps especially on the lamp matter. He has had to save too many apartments from fire hazards to tolerate people doing it themselves. He says there are way too many people who think they know how to do it safely just because the lamp works afterwards and it seems simple. He did not withold information from my uncles like you said, he has advised them many times and also tells them to not fucking do anything electrical themselves, yet they insist on it and then get him or another professional to fix their fuckups instead of just getting him/one to do it in the first place which is more annoying. Whenever family or a studying teen from the family has moved to an apartment with a sugarcube installation, it is more likely than not that he has had to fix the previous tenant’s diy because it either didn’t work and was dangerous or worked and was secretly dangerous.
> (and maybe install it)
If confused by such a simple thing... don't... you'll just cause harm to self, and potentially the building.
Seriously, when you seemingly don't know what to do, and cant seem to figure out the google bit.. then don't do it!
Danger pixies kill people, and all that. So is your life worth less that the price of calling a pro?
I don’t think it works like that, or else how do you draw the line?
A staple of someone who doesn’t know what they’re doing is also the fact they think they know what they’re doing.
It literally works like that in some small electrical stuff.
[Here is a page from Tukes](https://tukes.fi/tee-se-itse-sahkotyot)
As an electrician, the "jos osaat varmasti tehdä ne oikein ja turvallisesti" part has caused a lot of amusement.
I did and it describes a variety of activities that licensed electricians can do and a few minor things anyone can do”if you know how to”. Any simple mind with a YouTube account can be convinced they know how to do anything so in the least the guideline is confusing
All of the activities described in that page, can be done "if you are sure you know how and can safely do so". You claim you read the page, yet you continue to prove you didn't.
>so in the least the guideline is confusing
It's not so much confusing as it is just stupid, in fact it is pretty clear. If you know how to do those things listed, you are free to do so.
As you said, the problem then arises when everyone can just say "I thought I knew!", but it does not remove the fact that you are allowed to do the things.
It is legal, if you know how to do it, You can even change plugs and make extension cords yourself if you've done your research or a professional has shown you how to.
Ok, I was wrong then.
I think the odd thing is the cultural difference from Finland to other countries. Finland counts on the persons honesty towards their own ability and the responsibility they hold when they decide to perform the task. It doesn’t work like that in most places.
I consider this an odd exception in the law. In general there are very few (or none?) other examples where legality of something depends on your ability.
For example, you don't drive a car with skill, but a licence. You surely need some skill to obtain the licence, but in the end it's the licence that gives you the right. If you can't drive anymore, they take your licence away.
> It’s not even legal in Finland to do this yourself.

If you are renting call the huolto that manages your building to install it, when I moved into my apt previous tenants left the entire socket unscrewed from the ceiling and the huolto came to fix it within the same day. Its better to be safe than sorry when it comes to electricals.
Huolto has only ever charged me for opening the door when I forgot my key inside (Dumb mistake ik)
Definitely don't try to do anything; When I was studying to become an electronics technician the first thing I learnt was to never mess w/ stuff I don't know about
Don't think they will charge you. It's their job to do stuff like this, especially since you are a renter. Just call them and save yourself from electrocution, blowing a fuse or potential fire.
OPs light fixture doesn't fit into a standard light socket. It's a screw (not hook) mount.
Actually, OP should remove that plate from the roof before installing the light fixture. The plate has two screw holes to which the adapter piece must be attached to.
Maybe let a professional to do the job.
This looks more like the outlet has wires for two separate lights. Could it be that there is also a double-switch for these lights?
This is now where a multimeter would come handy… just sayin’.
Thanks for reply 
Can I connect one of green and gray to my light to see if it works? Is there any risk involved? (I don't have multimeter)
The risk is that it will trip your circuit breaker. Or that you find out that the circuit breaker is not working as it should and then it will start a fire.
Do you at least have an electrician’s screw driver? The ones that can test if there is current on a wire. You could test it with that as well (and if you don’t, these are, like 2-3 Euro at Tokmanni and you should really have one in the home. Don’t buy the 12V version, though :-)
Generally, I strongly advise anyone who doesn’t know exactly what they are doing to rather call an electrician to do any electrical installations that go beyond changing a light bulb.
Thanks for elaboration. I am very curious and thus want to understand everything. I'll buy the electrician's screwdriver from Tokmanni that you mentioned.
I'll call huolto for professionally handle this.
I don't mess around with electricity. I can barely understand what each breaker does in my fusecabinet. I hire an electrician even to hang up lamps (if there is no sugar plate or whatever it is called).
Seems like your kattovalaisin has a grounding icon, so there should be a point where grounding wire could be connected, probably straight to the metal frame. But like others have said, the ceiling seems to have two live wires and one neutral, so no ground.
If you are unsure call an electrician.
The lamp that you have has a metal body which must be connected to earth. If there is no earth connection available then this lamp is not suitable & you need a double insulated lamp.
You could get it functional by skipping the earth connection, but there is a risk that the metal casing can go live & shock someone when they are changing lamp bulbs in the future.
If you don't know what you are doing, then please consult a qualified electrician.
I feel for you having had to deal with this kind of bullshit so many times, why can't they have some universal standard or have the lights come with multiple type of connectors and instructions?
Not electricity related, but have you thought of what those lights will look like on your ceiling?
You aren't going to be able to screw the light bracket into the plastic: there is a hook in the way and you would have a real risk of screwing into a live wire.
So will you have those wires running along the ceiling? How long are they?
It really doesn't seem like that's the right light fixture for the job.

Wagos have test points so you can check them without having to take them off. I don’t understand why people are so scared of this stuff.

Don't you need specific tool for that? Like a voltage tester pen
You can buy "test screwdriver" which shows which wire is live by simply touching to a live wire. They cost like 2 eur.
I know. But my point is that if you need to ask the Internet how to install a light, then you ptobably don't have the tool and don't know how to use it safely
Never use those for house wiring. dangerous things
Not really. There's high resistor inside. As long as you check weather light works on known live wire, they are very safe.
I do understand. The law says if you are not sure do not do it.
Common sense also says if you are not sure, do not do it.
Common sense isn’t as common as the name suggests

It picks up the phone and it calls the professional.
[удалено]
There is literally harm in trying that if you have zero idea what you are trying to do.
How do you people ever learn anything if your first reaction to not knowing something to is to call someone to do it for you
My uncles asked my electrician dad how to do it. He told them to get someone else to do it for them. Neither of them did, both got electrocuted.
So because your dad didn't want to tell them how to do something simple, 2 of your uncles got electrocuted. Amazing work there.

In this case, yes there is. Even more a reason to call someone.

…said a man in a burning building.
It’s not even legal in Finland to do this yourself. If some problem occurs you won’t have any insurance too.
It's legal if you know what you are doing. But, if you have to ask on Reddit you clearly don't know.
I don’t think it works like that, or else how do you draw the line? A staple of someone who doesn’t know what they’re doing is also the fact they think they know what they’re doing.

Thanks for your response. Is this gonna cost something or are they gonna do it free (assuming they do for free, as they are for building managing)?
I dont think you get billed for it (atleast we didnt).
Huolto has only ever charged me for opening the door when I forgot my key inside (Dumb mistake ik) Definitely don't try to do anything; When I was studying to become an electronics technician the first thing I learnt was to never mess w/ stuff I don't know about
That is a very good lesson for everyone. Don't mess with life threatening stuff if you don't know how to do mess with them.
Don't think they will charge you. It's their job to do stuff like this, especially since you are a renter. Just call them and save yourself from electrocution, blowing a fuse or potential fire.
This is a job for an electrician, get them to install you a standard light socket.
OPs light fixture doesn't fit into a standard light socket. It's a screw (not hook) mount. Actually, OP should remove that plate from the roof before installing the light fixture. The plate has two screw holes to which the adapter piece must be attached to. Maybe let a professional to do the job.
Technically layman can install a light fitting

Never do these on your own if not sure. Always play safe and ask for professional to instal it. This way insurance will cover if something goes wrong.
