Hi all, just a quick question that hopefully somebody can help with.  When replacing a MCB for a RCBO or adding an extra circuit does the new breaker have to be the same as the CU or can anything that is BS60898 be installed? Example with a Crabtree Loadstar CU could I replace a 32A MCB with a 32A MCBO made by Wylex, or MK etc

 
they dont always fit, you need to be aware of the positioning of the buss bar in relation to the back of the breaker etc.  RCBO's also differ in height so they may clash with the earth or neutral bar....

 
As long as the board & breaker manufacturers say that they are interchangeable, or that they are not exclusively to be used with their boards/breakers etc. then you are fine, if either do, or, if they have made an announcement, either directly or thought their trade association that says they cannot, then you cannot.

I posted the reg. no. recently.

 
Sidewinder may have given up, I however have not.

Educate educate educate is the answer. Sidewinder recently replied on a similar question, and gave some very good examples of requirements and restrictions, and all to do with the makers (manufacturers) installation instructions and limitations.

Now I have the utmost respect for Sidewinder I have met him, and he has helped myself when I have needed his expertise, and I would urge all members to take his advise. Only a fool would ignore him.

 
I'm sorry to appear stupid , I've never had anything to do with the manufacture and testing of assemblies .    I never came across  those abreviations and had no idea what they meant , you don't in general contracting . 

I feel a right prat now .  

 
Dont forget that we now live in a litigatious world where if any thing were to go wrong and you had mixed manufacturers of mcb, rcbo, consumer unit, regardless of the fault the manufacturers would just walk away saying that you fitted someone elses breakers to their consumer unit and that their consumer unit had not been manufactured and tested to work with this other make of breaker regardless of the fact that all of this stuff is manufactured to british standards and therefore should work correctly together and leave you to take the blame for the problem caused.

I get the reasoning, but imagine all the cars being driven around with generic parts fitted, you don't hear insurers saying we are not paying out because you have Halfords break discs and not Ford.

That will be next, the manufacturers will say your car must be serviced by their dealers, family run garages finished.
