Shower circuit design.

Why would an electrician install a 10 mm twin and earth circuit protected by a B32 MCB for a 8.5 kW shower?

    Now I’m being told I’m over cautious and can lower one of the red flags.

    I'm not … research into accidents show that they happen because two or more things that could go wrong actually do: the “planets align” if you will.

    With three flags, one of which “might be OK”, still leaves two.

    Anyway, I don't necessarily agree with DZ(DS) that a minor overload on an OCPD “will probably be OK” - we don't have sufficient information to make that call (although you might Sparkingchip).
