Hi everyone need a bit of guidance, I have a shower to wire in an upstairs flat. It is an old fuse wire dist board therefore I am installing a shower consumer unit. The run of cable is only approx 4 metres as dist board is just on other side of bathroom wall. On the consumer unit I am going to install it has a 40A 30mA RCD and a 40A MCB will this RCD be suitable or will it need to be upgraded to a 63A 30mA RCD. The shower is only 8.5KW and will be wired in 10mm.
Thanks
