    I've got burners and an oven.
    Burners rated current=25A
    Oven rated current= 15A
    Total rated current=40A

    I wanna use 1 cable (Multicore PVC Insulated cable, unarmoured, one two-core cable, single phase) to supply power to both the oven and the burners.

    Lenght of cable from DB to isolator is 6meters and from the isolator to the burners and oven is less than a meter

    Installation method to be used is Method 2.

    When I select a cable for this installation I find that a suitable cable for this combined load is a 10mm2 protected by a 45A C/B. Now, i've never seen a 10 mm2 used for a stove before. Am I right with this cable size for a stove? Am I right in using the combined maximum rated current (40A) in sizing this cable? Where am I missing it?
    This is a good exercise as it has made me revisit those darned confusing tables.
    Now I see them in a second light and it's all fallen into place.

    If you use single core cables inside of conduit instead of a multicore cable, as you said you were going to install conduit, then your rating changes.
    The rating for a 6mm single core cable, installation method two, becomes 41 amps. Table 6.2(a)

    Normally the conduit and Flexi conduit will run from the distribution board into the oven and the rest of it is joined together with internal cables which usually have those heat-resistant cables and plugs.
