The oven is 2.3kw and the hob which is induction is max 3kw
What are the kilowatt ratings of oven ,and hob /What makes you think they are both 13amp appliances ?
The photo was taken when the old 6.6k ceramic hob was connected to the circuit which had the thicker cable. The new induction hob had a more conventional domestic appliance type cable with a moulded plug.More than a plug cut off ,it's had the original flex removed and Twin and earth cable used instead ,and no sleeving covering the bare CPC's in the connection unit( and very likely the same at the appliances ).
Installing a single socket for each ,and using correct size FLEX from each appliance to a plug is one way forward.
