    Domestic Installs Metal CU's also = Metal PV Isolators

    Interesting webcast yesterday from NICEIC covering the 3rd Ammendment BS7671, we were aware of nearly all of it. The one thing that made us sit up though was that in accordance with the regs, they specifically mentioned that the two isolators (and any other switchgear) needed for the PV system...

    Free: Various used commando outlet isolators

    I salvaged these from a job rather than skip them. Would need patching up, or suitable trunking arrangement to hide the various holes. Some have only one. They're going in the bin if not taken!

    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

    Fan isolators

    I know we all instal fan isolators but is this just a habit or a necessity. Could a double pole switched fcu be used instead, feeding a permanent live and a switched live via a pull coard? Just a thought or have I missed something?

    Due to the location of the Hob and Oven they are some distance apart so there are two isolators fed from the same feed so each items has an isolator within two meters as per regs - is it OK for these to be fed off the same feed ? I don't see any issues in practice I am just not clear about the...

    Requirement of local isolators for 3 phase motors on plant

    Normally I fit local isolators adjacent to 3 phase motors to allow for maintenance. I have been informed that as my main control panel is within 8 meters at most from any one motor on the plant I can install a lockable emergency stop push button to kill the control circuit and use this as a...

    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

    AC isolators - still required at CU?

    It has been a long time since I installed an inverter in a loft. I'm doing one tomorrow and I can't recall whether an AC isolator would be required at the CU. Obviously it would be at the inverter but I seem to recall the rules being relaxed for the isolator at the CU?
