Drilled through a cooler cable

[alexandruv]

Hello everyone,
The other day my girlfriend asked to mount something on the kitchen wall and I had to drill through the tile to mount it. Turns out i drilled through a cable which was powering the induction hob.

The power went off and the circuit breaker went down (the one outside the apartment, not the one inside). I live in a new block of flats in Warsaw. Usually when i mess something with the power inside the flat the breaker inside the apartment goes off - this time it was the one outside the apartment so i know i messed up big time.

Now, because i didn't want to remove the tile (brand new built in kitchen also) i decided I will make a hole from the other side of the wall and find the cable and patch it with a Wago.

Which I did - see attached. The problem is that once I turn the power on and turn on the hob.. the breaker jumps again.

I used a lexman multimeter to check the cable - the beep test and.. no beep

Does this mean the cable is damaged somewhere else too? How could this happen?

Thank you in advance for your inputs.

Disconnect the hob .
Try then. That's will eliminate the hob so you know it's the wiring.

From your photo, it looks like there may be damage further down.

Could that be causing the breaker to trip?

Agreed.

It might be prudent to remove some more plaster lower down.

If you use the existing wagos with no load lower down, is all good?

If not, and, I am not an electrician, it would look like the problem is further up stream.
