I currently have a 40amp MCB fitted in my CU for my immersion heater.
I don't use the immersion heater as I use gas so its only a back-up.
I'm changing the MCB's for RCBO's because I'm having an exstension built and need to bring them upto code.
I thought an immersion was normally fitted with a 16amp fuse? Should I get a 16amp RCBO keep it at 40amp?
Many thanks.
