Double pole RCD

MrJack96
Is there anything preventing us from using these type of RCDs for a 55-0-55 circuit?


the picture shows the original set up. And the replacement b27da3454a5814fd623eb7a7fef4edcb-huge-87007dcb-a17d-44db-b7f4-06ceebdf5a1f.jpg

    The original seems to be a D1 MCB with a vigi unit attached - in effect an RCBO - just checking that you're only suggesting replacing the RCD element with the RCCB rather than the entire unit.

    I had similar thoughts.


    First off check the original RCBO is suitable, it may not be performing correctly because it is unsuitable for the installation.


    Then if it is suitable, consider replacing like with like.
