I'm thinking of fitting a new consumer unit with MCBs instead of the set I have at the moment with re-wireable fuses.
Do all the common makes of MCBs, RCDs etc fit in all brands of consumer unit or do I *have* to buy all parts with the same brand.
I know thay all fit on DIN rails but do all the openings in the front of the boxes line up ok?
TIA
