Re: Ceramic Hob installation advice please…
I think have a word with the sparks first. all wiring like this has to follow not only electrical regs but also part p of the building regs.
if you get a spark in. make sure they are part p registered and see if they would let you route the cable. you could find they may not certify the installation unless the cable is routed safely and to their specifications
but saying all that unless it is a long run a 6mm twin and earth cable would be needed and another 32Amp breaker or possibly a 20Amp if its the oven. info should be in the books that came with the appliances
