Oven tripping the electrics

My guess is changing that cable to 10mm will NOT prevent the issue reoccurring as the problem to me is earth leakage not overload. 

If it was overload the cooker MCB would trip first well before the cable was overloaded as it is rated to trip at 32 Amps (7.4KW) which 6mm twin and earth can easily handle..

Your useful photos show you have a split RCD consumer unit with the cooker, “kitchen and bedroom sockets”,“downstairs lights” AND shower ALL running through the RIGHT RCD (leak detector), ( the one with the yellow button). 

All the MCB’s to the left of the LEFT RCD run through that one.

You have also confirmed it is indeed the RCD that is tripping.

When (not if 😉) it trips again, please tell the electrician to read my very first reply to your original post. 😁

All makes perfect sense, thank you. I’m thinking exactly the same and now I’ve re read your first reply I feel certain as well that this will be what is needed. 

I have been so well educated over the last few days 😅 
Can’t thank you enough for all your help.

Happy to help, that is what this forum is all about. I’ve been an electronics engineer for 30 years, but a good electrician can still teach me a few really smart tricks! 😊

How many amps are on the switch that is tripping?

See photo posted previously. It's an RCD that's tripping. They trip on 30 milliamps of leakage current.
