muffster, looks fine except it seems u've got the neutral from the hook up lead going into the main neutral busbar. u need to connect that into the neutral connection on top of the RCD otherwise the rcd will trip out straight away, or at least when u plug something into ur 13A socket. i'd still change out that 32A(yes they are 32A and 6A respectively)for a 16A or 20A MCB just in case. I know that the 'hook up' socket is 16A, Prob backed up with a 16A or 20A breaker, but if the socket is overloaded then its the breaker for the 16A socket that'll prob go b4 ur own 32A. 63A 30ma rcd is fine to use. Flex isnt ideal but should do the trick!!!!
