ᐅ Old Electrical Installation – Is It Possible to Determine Its Age?

Hello and thank you for the answers,

but to me that means: without an electrician, no real conclusion. 🙂
Does it help if I say that all lights (except maybe the attic) are connected with 3 wires?

Best regards

No, that doesn’t help either. What is your goal? Even old installations are working perfectly fine.

Hi hampshire,

Well, I’m a layperson in this area. We want to take over the house from my mother and renovate it, then move in ourselves.
Everything works perfectly, and there have never been any issues with the electrical system. The stove is on a separate circuit “as it should be,” installed by an electrician.
I just don’t know whether I should proactively replace the entire electrical system now or simply leave it as it is.

Best regards
Rüdiger

It wasn’t about giving a “definitive” statement. The request was for an assessment based on the picture of whether it is acceptable or needs replacement. There is clearly much more evidence supporting “it’s acceptable” than “needs replacement.”

From the picture, you can only tell that maybe the fuse or circuit breakers have been replaced or RCDs installed. However, the wiring inside the walls could still be 100 years old. In Diez, the colors of the cables and their quantity are different. Based on the colors, you can make some assessments. You can also ask Aunt Google about it.

Or also one in Limburg, which is right next door (but still in a different federal state). Always these spelling "corrections" ;-)
