I have replaced an old fuse style consumer unit with a MCB type. Lights and Fridge/freezer MCBs have been fitted. I need to connect RCD and MCB for shower and ring main. Shower is rated to be at 40 Amps with 40 Amps MCB and the ring main 32 Amps. What rating RCD should I be using?
The ring main is inside a small flat with no garden attached. Could I supply the ring main with a 32 Amp MCB only and use a 40 Amp RCD for the shower only?
