ᐅ Oven connection not routed through RCD/GFCI despite presence – is rewiring advisable?

Hello,

I'm currently replacing the kitchen and noticed that despite the protective earth conductor in the stove connection box, the RCD does not trip, and the stove box still has power even when the RCD is switched off.

A look inside the distribution panel shows:
The three phases to the three 16A fuses come directly from above at the RCD to the fuses, not from below, so they are positioned before the RCD.

Two questions: why was it done this way?
Is it now sufficient to simply connect the three fuses below the RCD?

Thank you

A glass cooktop usually does not require an RCD.
I would not recommend rewiring it.
1. You are not allowed to.
2. RCDs are only rated up to 40A (amperes).
So you would need a larger one or a separate circuit.
But why go through all that? What exactly are you trying to protect?

The new kitchen setup includes:
Oven, single phase, max. 3400 watts, hardwired with 3 conductors (including protective earth)

2-zone built-in induction cooktop with a Schuko socket, 3200 watts

Refrigerator (Schuko)

Ducted extractor fan (Europlug)

The plan was:
L1 - Oven
L2 - Socket (cooktop)
L3 - Socket (refrigerator and extractor fan)

What do you think?

40A per phase at the RCBO, also pre-fused with 16A. I would rewire it (or have it rewired 😉 ).
However, I would have installed the pre-fuse as a 3-phase circuit breaker.
Just my amateur opinion.

Thanks for the info!! Is there a reason to use end sleeves with the cables used here, or would 2.5mm² (4 AWG) copper wire also be acceptable?

So now it’s not just the stove but the whole kitchen?

Oven etc. must not be connected without an RCD!

Please don’t try to do it yourself.

I can’t see the fuse in this photo.
I only see an RCD that already handles 2x16A per phase and therefore cannot support an additional 16A.
