I’m hoping that somebody could give me some advice.
We recently had a new kitchen fitted, we had an excising double which is 4.1kw. This was wired into a consumer unit and a deducted cooker ring MTN132 B32 - 32amp breaker.

Our new induction hob is 7.4 kw.

The contractor has used the same feed from this supply to provide power for both my oven and induction hob. There are switches that isolates both appliances.

It is now been suggested somebody else, that this is incorrect, and that they should have ran a totally new power supply to the board. Reason being that it could trip the board if we use all our appliances, for example at Christmas or worse may be dangerous.

I have tested the system, in the best way I can by having all the appliances on and using all the hobs over a prolonged period. So far, all is good with no obvious issues.

Please can anybody advice me on weather I should start again and have a new supply to the induction fitted?

Thanks in advance.
