[QUOTE="binky, post: 478928, member: 490"] OCPD can be at either end of a cct, so if you had a 63A RCD that would allow 1off 32A MCBs and say a 20A and a 6A cct attached to it or 3 off 20A MCBs etc etc. I would argue RCBOs protect themselves in the same way, ie if you try to overload a 32A RCBO it trips out, so doesn't need an OCPD upstream of it.
