Ovens on cooker ccts

Farmboy
In domestic kitchens, what do you think of the practice of connecting ovens to 32/40A cb cooker ccts via dual cooker connection outlet plates? For example, along with a 6kw hob, a 2.5kw oven is connected via a 1.5mm2 3 core h/r flex? One view is that it's acceptable because the flex can't be overloaded and the cb provides s/c protection for the flex, nor would it be coded on an eicr.

    The MIs  you said specifically called for a 25A MCB or RCBO therefore they are not correct.



    Those instructions make sense to me - they're after overcurrent protection to protect the appliance internals and either an MCB or an RCBO (magnetic or thermal elements) provides that - an RCCB alone doesn't.  I might wonder why they don't like fuses - but perhaps that's just down to a lack of a 25A rating in the common series.

     

    If the equipment is to be permanently wired, then, EVEN IN THE SAME PRODUCT STANDARDS the manufacturer is required to state the acceptable installation method and protective device(s) that are acceptable, if this is important for installation. So I'm not sure where this part of the argument is coming from?



    That's good. So in the earlier example where the manufacturer's instructions didn't mention any maximum OPD rating, we should be safe to assume that a, say 32A MCB, would be acceptable.
