ᐅ Connecting an LED ceiling light – multiple wires hanging from the ceiling

Hello

I need some help again.

After decades without a ceiling light, I have now bought an LED ceiling fixture (metal and plastic).

This can be turned on and off or dimmed using a remote control.

The original light switch is probably no longer needed.

But now my question.

The building was constructed in 1963. Several cables are hanging from the ceiling. 😳 I don’t know which ones need to be connected to the fixture.

I’m attaching two photos for clarification.

Thank you in advance for any helpful answers.

Best regards

PS: Of course, I will switch off the circuit breaker beforehand 🙂

Brown or red? Red represented the earth until the mid-1960s = today greenish-yellow.
L black and gray N.
No idea what the green attachment is supposed to mean.

But be careful – in older buildings, everything can be different 😉

Thank you very much for the answer 🙂 – it could also be a faded red.

It’s best to measure everything first. Or check where and how the other end of the cable is connected.

Measure yourself – or (which would be my favorite option here) have an electrician do it. It’s common knowledge, but a lot can go wrong. The green wire might be a jumper. In older wiring systems, the neutral conductor was sometimes used simultaneously as the protective earth (classic neutral bonding), and the earth wire (if present) was connected to it as well. Today, this is a no-go, or at least a very delicate matter.

Are there electricians who come out just to test a cable? Are there people who actually call an electrician for that?

A practical person simply takes the lamp and touches the wires to it (grounding is not necessary for trial and error). Fifteen seconds and you know how the electricity flows.
