Dual fuel oven 5kw what cable size?

sid521 · Jun 29, 2023

The customer has suggested from a previous electrician that the oven requires a new circuit installed . Upon viewing the instructions it is stated that the total power consumption is 5kw and cable size should be 2.5mm .

The customer has a kitchen ring main with a previous fuse spur for a cooker socket .

Would this require a dedicated circuit as I believe you could use the existing socket

Oven is : Beko kdvf100k

Thanks

It can't be put on a 'ring main', and I suspect you don't mean a fused spur, (as in FCU) as that would be for a circuit 13A (or less).
The spec for the model you quote says 7.6kW, so perhaps a misunderstanding on my part, or by Bootskitchenappliances, from whence the clip below comes!
2.5mm might be a possible size for a multi-phase/multicore flex between the cooker and the connection unit, but surely not for the t&e supply cable.

Exactly I was wondering if the installation specs are incorrect after searching the model number for the oven . In that case it should be. 4 or 6mm cable on a dedicated circuit with 32a Mcb thanks

I think they have muddles up gas /electric in the specs.

It looks like gas does most of the stuff and says total load is only, 21000w.

I'm assuming the join to the ring is being done in a cooker switch ? And fed to a single socket ?.

As above. Mea Culpa. So much for Boots website info. I should have looked for the manual!

But now I've found it, the figures agree with the 5kW and 2.5mm cable.
There is a grill, described as 1.6kW, and two ovens, but no details of the consumption of the ovens in the manual!

The gas does all the hob, but where did you find the 2.1kW info? There are two ovens and a grill, and all I found was the 5kW figure

correction 21kW??

I can't remember some Chinese spec sheet online, which said, 2.1kw maybe that was for the oven.
