Replacing free standing oven with seperate oven and induction hob

[redmen1892]

Hi,

We are in the process of revamping our kitchen, currently we have a free-standing Hotpoint HAE60G which is hardwired into a Protek RCD protected by a 32A MCB, the total load on the current oven is 10.7 kW.

We have chosen a Zanussi Double Oven (ZKHNL3X1) and separate Zanussi Induction Hob (ZITN641K), the oven has a load of 4.3kW and the hob is 7.6kW, both require a separate 32A fuse.

Currently there is a 6mm2 cable that feeds the free standing oven.

I've had two electricians come and take a look, and I get a different response from both of them, one says the existing cable and circuit is Ok, the other one says I'll need a separate 32A circuit with its own 6mm2 cable.

Looking at the diversity calculation of the oven and hob, this would work out as 11900/240 = 49.5A, the demand of the first 10A would then leave 30% of 11.85A, if I then add on the allowance of a 5A socket would give approx. 27A.

I've read on other forums that you can have up to 15kW after applying diversity.

I'm now confused as who to believe , I don't want to embark on unnecessary the hassle of installing new cabling with the the guy pulling up floor boards and then getting a plasterer in , but if it's not needed and as long as its safe and it meets IEE regs.

Many thanks

Jon

The existing circuit is adequate - obviously proved by the use of the cooker.

Thanks, excuse my ignorance but the exiting cable that supplies the free stand oven does that get spilt in order to now feed the separate hob and double oven?

Electrician #2 either doesn’t know what he/she is doing, or is trying to create work.

If the oven and hob are close together then the usual practice is a dual appliance plate.

There are many other ways of adding to a cooker circuit for a second appliance.

Thanks, creating the additional work and obviously cost was my first thought
