32 Amp Cooker Circuit 13 Amp Cooker

[Jock from the north]

Hi,thanks for replying.The Beko Ceramic Hob is 32Amp/6.7Kw and cooker oven is fitted with a plug which I believe was installed when the kitchen was up graded by Magnets for the previous owners few years back. I was wondering if the 32Amp circuit will manage both loads without tripping the system. As mentioned earlier the circuit is a dedicated 32Amp for the cooker. Many thanks.

Hi do you know the rating of oven ,although it has a 13 amp plug it may be less than that .there will be a sticker on inside of oven door usually. Is your cooker switch with socket in a unit adjacent to oven

On the face of it, the Hob could use the entire capacity of the 32A circuit, so without further info the immediate response is - no, don't connect the oven to that circuit as well.

Knowing a bit more about the requirements of the oven, as above, would be useful.

The reality is that if you don't normally use the full capacity of the hob, then having the oven on that circuit would probably not normally trip the breaker. The old chestnut everybody quotes is .... when Christmas dinner is in the oven and lots of pans on the hob etc etc that's the one time it trips!

On the basis of the info so far, it would not be to regs to add the oven as well as the 32A hob on that 32A circuit.

The hob is rated at 32A and the oven will have a maximum load of 13A, although most probably less, so a total of 45A.
In my book, a hob over an oven can be considered as a 'cooker', and there is a diversity calculation allowed for these.
The formula is 10A + 30% of the remainder + 5A if a 13A socket is present on the cooker isolator.
10 + 30% of (45-10) + 5A = 10 + 10,5 + 5A = 25.5A, so well within the capacity of a 32A circuit.
