"electrical" question [wiring light fixtures]

Hello everyone,

I just moved to my new apartment. It is the first time I am dealing with fitting the lights and I managed with some help to have light in my bedroom and the rest of the house but in the living room I dont know how to fix the lamp.
There is a blue wire and a green one. The blue one goes from one hole to the other and the green one is hanging.
I was expecting two wires and be able to fit it in the same way I was able to do it in the bedroom.
In the attached image you can see how it looks like.
It is an old building. The fuses box is not inside my apartment and I guess it is just outside but it is locked down so I can not experiment with the fuses down.
My intention was to cut the blue wire and do the fitting. I want to avoid a nomination to the Darwin awards 2011.
Is there any advice you can give me or I should ask a professional to help me out ?

Thanks in advance,
Jacobo

Re: "electrical" quesiton

You don't cut the wires any more than you have to.

"There is a blue wire and a green one. The blue one goes from one hole to the other and the green one is hanging. I was expecting two wires and be able to fit it in the same way I was able to do it in the bedroom."

So how many wires do you have? In my simple mind one blue plus one green make two coloured wires. What are you expecting, three? Normally the blue wire is the low voltage neutral wire and the coloured wire (Green) is the live 230 volt wire. Any yellow/green striped wires are the safety ground earth wires which connect to the metal chassis of the lamp.

You MUST remove the fuses before working. As you have to ask these questions you are dangerous! Ask the landlord where they are.

After removing the fuses, connect the blue to the outside of the light bulb, and the coloured wire to the center of the lamp. How are you supporting the weight of the lamp?

It would be best for you if you had some help!

Re: "electrical" quesiton

Aaaahhhhh!!!! If you have to ask a question about electricity ..... rather employ an Electrician to do the job! Please! You don`t want to get yourself hooked up to Switzerlands electricity grid.....!!!!

Gosh, to me, people who even attempt to attach things to electric wires coming out of walls or ceilings .... are either VERY brave, or VERY dumb, or VERY innocent....?

Re: "electrical" question [wiring light fixtures]

Hehehe... no, no worries! I play safe, no risks taken. I didn't phrase well my first post.
The issue I am having is with the blue wire it is not cutted, so clearly the previous tenant didn't have a lamp hanging in there.
It is an old house and in the entire living room there are only electric plugs in one corner.
I am wonder why someone would decide not to use the lamp when u are so limited by the electrical distribution of the house.

Re: "electrical" question [wiring light fixtures]

Someone had a lamp fitted there at one time, I'll bet you a nickel the green wire is live, and they had it running through the green/yellow ground. For some reason that's somewhat common here, even acceptable.

Why the blue wire is there I've no idea, is there an end to it and it's just tucked back up there or is it just a loop of slack from a wire coming from somewhere and going to somewhere?

Re: "electrical" question [wiring light fixtures]

If you do a search on here, you will find several threads dealing with this subject. it sound like you already got a couple of fixtures hung...

However, as was previously stated, please have someone do this for you if you are not comfortable with electricity. Especially in these older buildings, wire colors mean nothing... And it is common to have "3-Phase" power rather than "single-phase".

There are several very good handymen on this forum who will gladly help you.

Re: "electrical" question [wiring light fixtures]

Has the blue wire not just been stuck back into the hole?

Cant you pull it out?

I have never had to cut a wire to fit a light...

Re: "electrical" question [wiring light fixtures]

It is simple, don't worry to much. But of course you have to put the fuses down.
The green one that have a plastic thing at the botton (from your picture) has to be left as it is. The other one you have to cut and connect to your lump. Just ignore the green all the rest will be the same you did with the others.

Re: "electrical" question [wiring light fixtures]

if the blue wire is continuous and not just folded back in the hole, then the green one should be too, creating a ring circuit i think they call it. If the blue is free then the blue and the green will fit into what they call a douille in french which is a temporary light fitting just to see if it works. However, without cutting the fuse, and i cannot believe that you dont have access to your fuses, after all that is essential in any case if a fuse blows, then only a qualified electrician can work on it simply by switching off at the switch. you cannot because you wont know which way is off and on, he will have equipment (a volt meter) to check it.
So as you have been told, get a lecky in , if you have to pay for one, you might as well get all the things you want done lined up because once he is there the work is not expensive. also ask him to make a report on the state of the electrics in your flat as it looks to me like you might need it later on.

what?????

if I'm reading that right, then DO NOT DO THIS!!

as others have said swiss electricians follow there own colour codes, looking at your picture blue should be neutral and green should be live, green and yellow should be earth, I say should be, but who knows, get yourself a volt meter and check, but if you are in anyway not sure THEN DON'T TOUCH IT!!

The blue wire looks like its just been tucked up to stop you electrocuting yourself, but if you follow some of the advise on this thread then YOU WILL ELECTROCUTE yourself.

For the sake of a few CHF to get someone who knows what they are doing, you'd be mad not to.

ETA usually the neutral here is always on, ie its not connected to the switch in anyway, so even with the light switch off YOU CAN STILL GET A SHOCK

Thats totally wrong seyon , the plastic thing is a connector block and a cheap one at that, it should be removed and the wire connected to the light fitting directly, the earth wire may or may not be necessary, the blue is the neutral (or maybe the green is i dont know) but those are the two that must be fitted to the appliance.

What terrible advice. You have no idea, by looking at the photo, which of those wires is live or earth (and I have seen live wires coloured green/yellow in Switzerland ).

"Cut and connect" - He now has two ends. Connect which end? Do what with the other end. Why would somebody suddenly need to cut into a wire that looks as though it's been there for years?

If the OP can't test the wires himself then he needs help from someone who isn't just looking at a picture of some wires.

Agree absolutely - I had an occasion where I dropped all the appropriate fuses and still got zapped by the "earth".

Lesson learned. In Switzerland it's definitely worth having an electrician .

Re: "electrical" question [wiring light fixtures]

I was hoping this was something common and there was a clear answer for that. I will try to find someone who can have a look to this for me here in Zurich.

Thanks for the answers

Re: "electrical" question [wiring light fixtures]

electrics here are nothing complicated, much easier then the uk, BUT there really doesn't seem to be a standard colour code here for wiring, which is really very odd, we have different coloured wiring all over the place, and I have seen places where all the wires are the same colour.

so unless you know what you're doing, and most importantly have the tools to test if wires are live, then don't touch!!
