What happens to BS EN 61439-3 approval if a non-standard MCB (or RCBO, etc.) is fitted?
I have always been a great believer in fixing rather than replacing.
I would say that it is perfectly reasonable to fit a non-standard part when the alternative would be to replace the whole board (due to obsolescence, for example) provided that it is done with appropriate engineering judgement and skill.
The other proviso is that you have professional indemnity insurance in place for your design work.
