Advice re oven and hob wiring

[john Stevens]

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.

Right, thank you. So in my case both my combined appliances, oven and hob equates to 11500kw. Taking that into account and factoring in that 6mm is in use makes the 32amp rcd prictected board breaker/fuse suitable?

i hope you meant 11500watts, not 11500kW. .
in which case, it's 10A + 13A = 23A design current. ( add 5A if a socket is on the isolator ).

It's a super fast cooker if it's 11500kW

...or a small nuclear reactor, with rings?

You have tried it with all appliances on and it doesn't trip, don't worry about it.

 

[john Stevens]

Yes ok guys! Don’t think I will be pursuing a career in electrics .... ever

At least you have thought about it and seeked to find the right answer. Most people wouldn’t care, as long as it switches on and works

Now you should have a different concern: whether you want to continue using the 'electrician' who has never heard of diversity and further more cannot accept the principles of it...
