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.

    It helps to know there is a low insulation test result before you start breaking the installation for further inspection and testing, you also really need to know the insulation resistance of the complete installation as it will be used, rather than just the insulation values for each individual circuit.


    A couple of weeks ago whilst left home alone I spent some time watching YouTube videos by guys demonstrating inspecting and testing both for EICRs and general fault finding.


    One well known presenter was fault finding garden lighting that was tripping its RCD without using an insulation tester, he looking for then correcting obvious faults, then bang testing it. If you don’t get a test result before and after working on the installation how do you know if you have really sorted out the problem?


    It is a really clever electrician who can find all the insulation faults by inspection.
