Circuit Requirements for built-in ovens?

    Hi, I'm reconfiguring our kitchen and intend to install 2 built-in Neff ovens. One oven is rated at 3.45Kw the other at 3.3kw (both max loads). Do I need two cooker circuits or will one 6mm T&E circuit with with two boxes and a 32amp fuse suffice?
     
  2. Should be fine, just DIY here. Reason is:
    32A * 230V = 7.36KW
    3.45 + 3.3 = 6.75KW

    Add in diversity (both ovens won't both be on full tilt, at least not for any serious amount of time).

    Terminating 6mm into an oven should be fun:p

    When you have got a bit more experience and a bit more upstairs between the ears you will discover that it's not that hard to terminate 6mm cable if you possess the necessary intellect and tools.
    I've terminated 240mm armoured cables a few times it was easy to me but it's not something you would be capable of.

    Most kitchens we do now we run 1x6mm for an induction hob and 2x2.5 20A feeds for 2 ovens or an oven and a microwave/combi. If the ovens or microwaves come with a plug then we fit a socket onto the end of the 20A radial or a DP switch if they are rated higher.

    How on earth did you get the 240mm2 in to the oven?

    I saw someone manipulate and terminate a 180mm2 3 phase armoured once like it was a bit of flex, I struggle with 3 core 25mm.

    The bigger the cable the easier it is to terminate. The difficult part is the physical weight of the thing, like wrestling a conger eel.

    Thanks for all the advice (and banter). I'd rather keep it to a single circuit if possible hence the 6mm with two boxes.

    They do make a dual outlet box for cookers.

    Dual outlet plate would be your best bet, as Spin suggested.
