Hi al it’s not. DIY job I’m aware of that. But I have just purchased an electric range cooker. Had an electrician out to extend cooker cable and he told me the instructions Manila of the cooker required a 40amp MCB. I’m not really in the market as of yet to be changing the consumer unit and I wondered if anybody knew where I could get a 40amp rated MCB for my very old GET SCHUPA consumer unit or if there are any “compatible” ones floating around?

I’m not sure if this is correct . But I thought 13kw would draw around 56 amps therefore surely I would need a 60amp MCB? Is that not correct ? I’m just paranoid

I will get round to having the consumer unit replaced when the rest of the house Reno is finished

The cooker is not likely to operate at is full possible loading. All heating elements would have to be on and cycling simultaneously at the same time, this is highly unlikely. Leave the 32A and see how it goes.

Manufacturers like quoting bigger numbers than competitors .
Ovens are not meant to be space heaters -- That's why we shut the door , it warms
and power consumption drops.

You say that, but with the missus cooking three different meals...one for me one for her and one for the daughter ....

So the 13kw is with the oven, grill and all 5hobs on at the same time?

Is the cooker connected and have you tried it.
It’s not connected. We got the oven from AO and paid extra for fitting. But as we were told the fuse needed upgrading they wouldn’t connect it up. I mean if I turn the MCB off I’m sure I can wire it in... it’s like changing a socket surely?

Stove installation experts (are keen to cover their asses).
I can remove it for you . On to next job asap...
(Upset with non fire rated light fitting - still sitting "pristine" where it could
become part of a chip pan fire disaster )
I may remove it when Mr parents move , for a more trendy re-fit !

I hope you asked for the fitting fee back.

That board looks like a Wickes one. Don't know if they still do that model.

By the way manufacturers instructions are guidance only and don't have to be followed if they are wrong. It appears they are wrong in this case.
