Applying diversity

Sam Spark

When calculating the load to size a cable for a cooking appliance, do you apply diversity?  For clarity , I do but not sure I should.

    indeed it is OK, for a multi element machine unless it is credible that all the elements will be on full chat for a sustained period - and here sustained means like more than 15 mins.Given the way thermostats operate, this is most unlikely in a domestic setting.

    Also true if the oven and rings are separates but share a feed.

    But something that has a single element that perhaps operates a pressure cooker, or heats a serving counter, maybe not a safe assumption.
