    Hi just wondering if anyone would know this, regarding sak din rail terminals when are separation plates really required obviously at the end of the sak so no exposed terminals but are needed between different type terminals such as live and neutrals or is this just a preference ? Thanks in advance

    Like all those type of semi exposed terminals they just clip up tight next to each other the caps are for the exposed ends..

    Aside from at the end of a row I would probably include one when placing a smaller terminal next to a larger one if this would leave metal work in the larger one exposed.

    Between connections for outgoing feeds is where I would use them, they make it obvious where each separate circuit is. Some of our terminal chambers had up to 2000 SAK terminals.

    We put them between terminals of different voltages and circuits


    0v & 24v
    often these are in linked rows
    using screw in jumper/ link bars
    Segregating with an end cover ensures one jumper can't touch the next one

    motor / mains power 240v /400v terminals are segregated from other terminals/ circuits and usually have combination of earth terminals, end covers and stops on both sides .
