    Rotary isolators

    As above, can any recommend a decent brand, I've been using 63a & 100a IMO Stag branded ones which have caused me no end of trouble with screw heads shearing off with minimum force, I've changed the guts on 3 of these and now lost total faith in them. Cheers

    Using rotary isolators for switching loads on and off?

    Hi Can you use rotary isolators to switch resistive loads on and off on a regular basis (talking 18KW load here) I personally thought not, that it should be controlled through a contactor but I have seen another installation that is using isolators thx Bigfoots
