16A oven ok on existing set up?

[dksanders]

What?

Its a friggin domestic oven.

..and many domestic ovens require a dedicated feed, especially double or multi purpose ovens. Until the OP just posted the manufacturers information, he'd listed the power consumption which totalled 11.2Kw which would draw 48Amps.

Hi dksanders,
I got the oven figured from the manual. Photo attached. I presume that I have read them properly?

Thanks Fletch, is there a section describing the electrical connection requirements?

The only thing it says is the wording on the picture attached. But not sure what that really means?

 

[dksanders]

Thanks Fletch, although the English is somewhat questionable, ("the power mains....") that confirms that the oven needs a 16A supply so my previous comment about changing the MCB to 40A as long as the cable is suitable applies.

I must be getting my maths wrong.

If I was calculating max load using diversity, for the listed W loads, then I would be going for 40A supply. However, as previously posted, the manufacturer of the new oven, has listed a max supply requirement of 16A. Presumably they have applied their own 'diversity', due to the users limited selection of elements by control knob. But in any case we agree on a max load for the new oven at 16A.

The only other unknown is the hob, which is rated at 5800W. Which I obtain a max load in A's (after diversity) of 14.5A.

So why the need to change the ocpd, when the existing 32A appears suitable?​

think some members think a domestic oven is a pot bank kiln.

Not knowing enough about how the oven can be used i.e. if all those items can be on at the same time, (think Xmas dinner cooking), and likewise for the hob, I didn't apply diversity.

Thanks everyone for the feedback.

I can use the fan oven on its own, or the grill on its own, then either the top or bottom element on their own or together or the grill plus fan. So I think it’s probably fair to add diversity into the equation.

You need to go back to school.

We had a range cooker, who's installation 'engineer' would only connect to a 40A supply. It had a facility where the all the (could be turned on) ovens could fast heat for 7 mins. I clamped it, along with switching on the grill & side oven; never got more than 14 A.

and why do I need to go back to school..?

Cos I think you got your maths wrong? No offence (someone's else just called me rude).
