Connecting ungrounded electrical cables to light fixtures - electricians' advice requested

I think this is well outside the realm of iffy territory such as medical and legal advice. I suppose we’ll see.

I went on a fairly major shopping spree at IKEA earlier today in order to furnish my new apartment, and on the list were some ceiling light fixtures for the bedrooms. The fixtures themselves did not come with a socket plug, and so I purchased ungrounded contacts after determining I could use them with the fixtures.

So: the issue.

The fixtures have a plastic connector into which the wires that run to the bulb have already been inserted. One is beige and inserted in a switch (I don’t know the proper term for the little jobby you press down on with your finger to insert the wire and clamp it into place) labeled ‘L’; the other is blue and inserted in a switch labeled ‘N’. The contact has one brown and one blue wire, and the instructions back up my assumption that the colors should be matched if I don’t wanna blow a fuse or start a fire. However, both the ‘N’ and ‘L’ points have two holes for each clamp. Looking down at the connector from the top, the wires appear like so:

 .  .____ L (beige)
 .  .

 .  .____ N (blue)
 .  .

The question: Where should the brown and blue wires of the contact go? Should it look like this –


_____.  ._____
     .  .

or this?


     .  ._____
_____.  .

Or does it not actually matter?

If I understand your question / diagram, it doesn’t make any difference - both holes are connected to the same wire.

OK, I just didn’t know if having the wires touch directly would create too much heat for the connector or something similarly bad.

If there is any heat at all, something is not right. If you could post a photo, it would help…

I think the batteries on my digital camera are dead but I’ll see what I can do. In the meantime, I got a look at the wires coming out of the ceiling and from what I can tell, the brown wire and blue wire are reversed, so if the lamp gets plugged in, the brown and blue wires cross at the socket. That’s gotta be bad, yes?

OK, pitchers!

First up, this is how I connected the contact (at left) to the fixture wiring (at right).

This is how the ceiling wiring looks.

This is how the contact wiring would look if plugged into the socket.

Apologies for the crappy quality, I gotta learn how to compensate for shaky hands. I hope this clears things up for whichever electricians are looking in.

That all looks fine to me.
Although, I’m in the US, so I’m not completely sure about your odd European electrons. :smiley:

Well, looks like I got light in my room. Nothing went ‘pop’ and don’t see any flames coming from the ceiling. Thanks!
