    What would be the electrical requirements for a 10kw 230v mira elite st shower on a 15 meter run? E.G. Cable size, rcbo size etc.
    Totally hypothetical question.

    45amp rcbo
    10sq t+e
    45 amp isolating switch

    I would think

    you'd also have to determine that the installation is suitable for the shower load

    I'd prob fit one of those pullcords

    50amp quality switch
    I've used Crabtree on 10sq and they're better than the type that takes a box

    And what is the primary function of the isolator on such a shower

    Yes, that is what a double pole pull chord is, an isolator.

    "An isolator is not the same as a switch. It should only be opened when not carrying current, and has the purpose of ensuring that a circuit cannot become live whilst it is out of service for maintenance or cleaning"

    The OPs question has been answered and we have a good explanation of why local isolation should be provided for a fixed appliance such as a shower.

    Lets leave it there before the thread becomes a train wreck :)
