Complete noob here.
I'm finishing building my kitchen and the last part – the wiring of electrical oven and glass cooking plates, is presenting me with some challenges.
I am located in Germany.
The oven comes out with a 3 pronged cable (I guess active, neutral and ground?).
The cookers were sold to me with no cable.
There is one junction box at the intended spot in the kitchen, with 5 cable grips, which is definitely 3 phase.
I'm wondering what's the best course of action with both the oven and the cooking plates.
My thoughts so far:
- Is there a way to connect the cooking plates to the same junction box as the oven somehow, without blowing things up?
- If not, should I just connect them to a nearby socket with a cable ending with a regular socket plug?
- What about the oven (single phase cables) vs the junction box (3 phase)?
Note: the sockets seem to have ground clips here – see picture below.

Get a mm and check the voltage between the wires (phases).
Ignore the green/yellow for this.
If the black is neutral (likely) then the voltage between any of the other 3 and the neutral should be around 380V.
Between any 2 phases (brown, gray, blue) should give you 230V.
So, as the load on phases should be balanced, I suggest you get a competent electrician to check and connect this for you. That way (s)he can check which appliances are on which phase.
I had an issue with my hob.. puled the oven out to clean it and a wire popped out for the hob. Not thinking I put it back (blue to blue)... Massive bang and off to buy another hob :) happy days... Made sure of the voltages before connecting the new one...
