3-Wire Chandelier Configuration: Connecting 4-Bulb Chandelier with Dual Switch Control

Hello,
I wanted to ask how to connect the chandelier in a 3-wire configuration. In the simplest words, 3 cables stick out of the ceiling, which go to the box, and also 3 cables from the box go to the light switch. The chandelier would have, say, 4 bulbs, and it would light 0 (switch off) / 2 (on the first 'flap' of the switch) / and 4 on both 'flaps'.

I have searched a lot on the internet, but unfortunately there is either a 2-wire or 4-wire connection described everywhere. Some people said that a 3-wire connection is impossible, but I used to have a wiring diagram in this way, unfortunately I lost it ...

Does it need a special chandelier for such a connection? Are they universal in this respect?

If you need a diagram, please let us know - I will draw it.

Thank you in advance for your help.

Greetings.

write what colors of the wires come out of the connection (most likely blue, brown and yellow-green); with this configuration, you can connect it to 0/4, i.e. either all are lit or none


have you not written whether it is new or "old" installation?

I assume that the chandelier also has 3 wires and the switch is double. So it looks like this phase you have at the ceiling divided into two and neutral for this. and in the chandelier it is the same.
I did it so that I screwed on the same lamps in the chandelier (all) and checked with an ordinary ohmmeter between which outputs of the chandelier have the highest resistance and these two are phases. later it is easy to check that from each phase to ground there is half of this resistance

there is no concept that says that it is impossible to connect 3 wires because half of the chandeliers have this

Hello!

My friend primo82 please see this topic: Link .
Diagram for three bulbs, so for you, connect two to one key (in parallel) and two to the other.

Hello,

The installation is new, done by me. The cables in the box are also not connected yet. The colors of the cables are as provided by mr_kciuk.

I have read the link from jdjan1 and found a diagram of interest to me:


Looking at this, it is not necessarily 0/4 joining, you can even do 2/2 and 1/3. As I understand it, I just have to connect the phase wire going to the box with the two wires going to the chandelier, and the neutral wire going to the rest.

I just wonder what about the cables for the switch, because according to this diagram there should be two and I have three ... (Installation in this room does not have a PEN cable) Do you also connect two into one or just leave one unused? (Although I know that in this diagram that I used to have all the wires were used)

Greetings.

You have PEN for sure - you just do not have N and PE separated into separate ones, i.e. the installation of the older type TN-C; The PE vein is unused; for 2 keys, as in the picture you need 2 phase wires and a neutral one, with N there will be no problem - you take blue, one of the phase ones - brown for sections I, now there is power to section II - conditionally you can use yellow and green, only and exclusively when you clearly mark on both ends that it is no longer PE - mark it with paint, electrical tape, no matter; there must be a clear and permanent indication that there is a change in the use of the vein !!!
Next: you connect neutral in the box and you pass the phase wires through the bipolar connector
As for the connection of the candlestick itself - write what the cube looks like and how the colors are preserved (I hope that the 'foreman' was not hung over when folding and kept the colors with the standard ); from the description that there is a 3-wire connection, you have a simple matter: blue-blue -> neutral, and the other two are phases, with a small exception: as you will see yellow-green on the chandelier, God forbid you connect the phase !!

Hello!

I can see that the connection is not fully understood by my colleague.
In that case, please watch more: Link .
In this document it is a diagram with a series (candlestick) switch.

PS The technical language is not prose, but a diagram, characteristics, table of measurements, etc. Hence, my answers are limited only to this kind of statements.

Besides, it is a pity that when you did this installation, you did not think about the PE cable to the chandelier (grounding), i.e. a total of four wires. This is required by the regulations and common sense.
And, as mentioned above, you must never use the yellow-green wire as phase or neutral! This color is reserved only for the PE conductor. If you play something else on it, it is very possible that it could cost someone your life in the future.
Similarly with the color blue - only neutral.
With the phases, however, we have freedom - white, gray, red, black, brown, etc.

In the will to be exact, since you did this installation yourself, I hope that you led to the sockets for 3 wires, not two ... And do the sockets at least have a 2.5 mm cable and secure it? 16 A, 1.5 mm light and 10A fuse ...

Hello,

jdjan1 - this is the pattern I meant, now it's all clear. There should be no problem with connecting. Thanks!

The installation has a PE conductor (or rather PEN, because it is an old building, additionally this is what an electrician friend recommended to me and so I connected it), but only in the kitchen. The chandelier is in the room, and it does not use devices with a "pin" there, so the PE wire was not connected (except for one socket to the computer). Indeed, I could have thought about the PE cable for the chandelier, but I will not be making the walls again now, maybe at the next renovation.

Thanks to everyone for help and advice,

Greetings!

Hello

There is no big tragedy with the lack of a PE conductor (I'm talking about practice) due to the fact that a large part of the lamps do not have such contact.

greetings

How is the TN-CS installation and there is a PE wire, with a metal lamp housing, what's the problem to screw the protective cover to it?

No.. The situation is that I do not have this lamp / chandelier yet, I will probably buy it during the weekend, then everything is clear.

Greetings.
