MCB and RCD mix and match of makes 536.4.203

Stewart Mason
Just wondering what peoples thoughts are to mixing makes of MCB's and RCD's in consumer units. I went to a callout the other night and the culprit was a faulty 61008 RCD. To get the power back on I replaced the faulty Item with a different make of 61008 RCD. The next day I raised a job to have the right make of RCD fitted. It turns out the QS at work isn't concerned about the incorrect make of RCD and is more concerned about IP ratings being met. Am I right in wanting to fit the correct make of RCD?


What would you code this as on a EICR?

    Most important is does it fit the terminals properly and not put strain on the enclosure or adjacent breakers ?

    in general the risk of mix and match is small, if it is done properly, and you are not right on the edge of PSSC spec. or relying on co-ordination of cascaded breakers.

    However, if you want to cover yourself liability wise with maker's type testing, you can bet that combination is not covered, and if it caught fire you'd have no comeback.

    But you'd  almost certainly have not got much out of them  anyway, even following instructions to the letter, unless your legal team is as good as theirs.
