    Hi All,
    I am installing two new showers, there are already two electric showers in the house. What do I need to install in order not to overload the system ?

    I was told I needed an Isolater or a Lockout switch.
    Can someone help ?

    Please

    are you standard domestic 12kva?


    are they all instantaneous showers?


    2 is prob the most i'd put on a 12kva supply with a non-priority setup

    hardly worth it with 3 or 4

    Even just 2 electric showers requires an interlock unit really. 4 electric showers would seem a bit pointless unless its a huge house with 3 phase supply.

    ya only 1 at a time on standard supply

    hardly much point having 4 instantaneous if you can only use 1

    A bit pointless alright. Maybe 2 on the interlock and a power mixer shower.
