How to connect a multi-track chandelier with grounding?
I have a multi-path chandelier (5 horns). Three wires come out of the chandelier: phase, zero, and ground ... I want to connect two switches on two keys so that two and three horns burn and grounding is necessary, how to do it right and best?
My version: use the ground wire as the second phase, but what about if you need to do this and ground the chandelier. Three wires also come out of the ceiling: phase, zero and ground.

It will most likely be right for you to use a radio relay for chandeliers. A relatively inexpensive device and alterations with it are not much needed. In addition, some models can be controlled with a single power key. One click - one group, two clicks - the other or both. The block is placed in the chandelier itself, in size it is like a pack of cigarettes. Well, in the chandelier itself you will have to make an exception for two groups of lamps. It is recommended to ground the chandelier, but not necessarily, just for the time of maintenance it is necessary to observe safety measures and completely de-energize the machine. Since ground is coming out of the ceiling and earth is also coming out of the chandelier, of course, ground it by connecting the wires of the same name.
The scheme of connecting a five-arm chandelier to a double switch is provided in the article https://our.electricianexp.com/en/sxema-podklyucheniya-pyatirozhkovoj-lyustry.html
And if it is not possible to install a relay ... can I put the phase and grounding on one wire? (That is, take the green-yellow wire for the phase from the chandelier, add the same wire and ground the chandelier at one end, and connect the other end to the phase and connect both wires to ground from poiolka?) Thus, to kill two birds with one stone .. the function of grounding from the ceiling will simultaneously perform both phase and grounding ..?
Some kind of porridge. In your situation, where does the yellow-green wire go? If it goes into the box and connects to the same ground wires there, you need to disconnect it from them and only then use it as a third wire for the chandelier. You also need to find the wires from the switch in the box and determine the wire from the second key, connect it to the yellow-green wire from the chandelier. Now, two wires with a phase from the switch and a zero wire should come to the chandelier. Do not use the ground wire as a working zero, as in the event of a zero loss, the instrument housings will be energized !!
Sorry, I didn’t understand something ... I have a purchased chandelier, it was originally assembled so that all the horns burn at the same time ... that is, only three wires come out of the chandelier: blue - zero; brown - phase; and green and yellow grounding ...
From the ceiling, that is, from the box, there are also three wires: blue, brown and yellow-green, I don’t remember the switch ... I think there is a jumper from brown wire to green-yellow between the two keys ... I can only see tomorrow ...
Now everything is clarified, you need to redo the connection diagram in the chandelier itself. Leave a light bunch of wires unchanged - this will be zero.
Disconnect the dark wires and divide into two groups of lamps, and twist. Remove the yellow-green wire with washer from the chandelier.
That is, in this case, make a chandelier without grounding ...? And these are the wires in the switch ...
And these are wires in the switch, but to my surprise, there is no green here ...
Judging by the photo, you have already turned off the switch, i.e. two phases go to the chandelier. It is necessary to trace where these wires go. Are they in the box? Where do they go next?
I connected a five-horn ... thanks, but an eight-horn ... I'm confused because the wires from the chandelier are all the same color ... how to help please ... I understood the two-key principle ... it remains to determine which wire is zero and which phase?

One of the wires going to the lamp, set to zero. That is, collect one wire from the horns in a heap, it will be zero. Distribute the remaining ones into groups, these will be the phases of the groups.
