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.

    To state the obvious, you can insulation test a built in oven from the consumer unit and test earth continuity with a wander lead, again from the MET in the consumer unit.


    So at most you only need to slide it forward for a quick look behind it.

    You're correct, in part, but if just sliding it forward for a quick look, what of polarity, and where is the circuit extremity for Zs, arguably at an outlet plate, which you need to get the oven fully out to access (if one is installed), and if connected straight into the unit, then at the unit. And what if you see the oven and/or hob are connected via t&e? Is that an FI because although the regs allow it, what of manufacturers instructions that usually specify a flex. If you're sliding it out for a quick look, you may as well lift it right out and check the lot.
