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?

    Hi Andy,

    Firstly the Manufacturers instructions are paramount and should be followed and to be fair if non type-tested accessories i.e. MCB's are installed the EICR is worthless (not to manufacturers instructions). To be honest the MCB's should be changed and a Minor Works certificate should be issued.

    Worse case scenarios a C3 placed on a condition report if all the markings are visible on the breaker etc. and the occupier informed, if no markings are visible on the breaker FI should be indicated and this would be unsatisfactory and would fail the EICR.
