Hello everyone,

after having done many things myself in our semi-detached house, I now wanted to replace a basement window. The current window is made of wood and is quite shabby. According to the instructions, it seems pretty simple, but I have a problem:

A cable goes out of the house through the window, is attached directly behind the window to a kind of metal clamp, and from this metal clamp another cable goes back through the window. After doing some research, this should be the foundation earth (?). My question now is: Is that correct? And how should I deal with it? Am I allowed to simply disconnect the two cables for the window replacement? Attached are two photos.

Thanks in advance!

Best regards, Marius

The grounding electrode should be the driven rod on the left at the terminal strip that you photographed. From there, a thick cable should go to the distribution cabinet.

Your cable at the window may additionally go outside to the roof drainage or something similar (perhaps to protect against electrochemical corrosion)?

But are you really sure that both cables are single-core "green-yellow" cables connected to the terminal strip and not something completely different, for example some retrofitted mailbox lighting or garden socket or something similar?

Photo of the cable on the metal clamp. The foundation earthing is the rusty thing on the left as already mentioned.
