Hi all, i have a mem 2000 consumer unit which i would like to install a shower circuit to. I think it is a split board because it has a 100a 30ma breaker in the middle with 4 breakers to the left marked shed , kitchen , dish washer and sockets. To the right there is another 5 breakers with a spare space -cooker water heater, lights, washing machine and one which is 100ma. Do i need to fit an rcd to the shower circuit ? would it be ok to fit it in the spare space on the right hand side ?

You do need RCD protection for a shower circuit, do you know which said split is RCD protected, I would suggest using a 45a RCBO on the non protected side but not sure there is one for the mem 2000 board.
What spec is the shower? output/voltage and do the manufacturers instruction recommend a breaker sizes?
easiest way to determine rcd protected side is press test button and see which circuits trip. Then reset for return of power.

If installed on the RCD side a MCB can be used.
You need at least 40Amps the cable size will depend on the run and route taken if not grouped with other circuits and not run through thermal insulation, you could get away with 6mm twin and earth, if clipped direct.
But best if 10mm is installed for later upgrades for higher powered showers.
I do recommend a competent electrician is used to carry this work out.
