    How many different brands in one board?

    EICR today on a holiday cottage. Suffice to say they’ve agreed to a board change along with some other remedials. I took the cover off…. That’s not one of the faults… but straight away missing busbar shield, mismatched devices no RCDs whatsoever and 1.5mm cable spurred off a 32A mcb.
