    Correct application of diversity, separate hob/oven on single feed.

    Hi,he What is the correct application of diversity, when a separate hob and oven share a single feed. As far as I see it, electrically they are the same as a free standing cooker - or does a cooker have a limiting mechanism to prevent all circuits from working at the same time. Hob is 6.7kw...
