Installing 8.5kw shower which will pull 37 amps, looking at shower cu with rcd, but it comes with 50a mcb will it be ok to overrate or should I change the mcb to 40a.

You would be better of fitting a 32A as mcb should be the same as or lower than the current carrying capacity of the cable as your mcb is meant to protect the cable if I remember correctly thats for 6mm cable or as the post above

you sure about that acat nobody mentioned the installation method but method C 10mm is fine on that mcbDecided to have a look if you use the 50A mcb provided it should be on a 16mm cable
