Will a combined MCB/RCD plug into most consumer units?

...or do they have to be the same make as the original CU? E.g. will a GE MCB/RCD fit my Proteus CU?
 
No, you need to use an RCBO the same brand as your CU.

This is because thinks like busbar position and shape, din rail position, breaker depth, breaker width, etc varies between all the manufacturers.

Also using the wrong brand does not ensure compliance with the CU safety standards.


Proteus RCBO These will be availavble from any branch of CEF
