[QUOTE="SPECIAL LOCATION, post: 523352, member: 250"] No one has talked about burying anything into a wall....? As it looks to me like the CU is in a cupboard type area.. Its probably easier and neater using some surface trunking for the short distance to the CU.. Or if a suitable knock-out lines up with proposed cable position, a length of PVC conduit straight into the CU... And with a suitable hole aligned with the floor void can go straight out onto external wall at the other end.. So dependant upon exact building structure, cable run could be done without any need for RCD protection.. certainly not impossible. Plus as ProDave pointed out those RCD's are a bucket load of inconvenient random tripping waiting to happed with so many MCBs supplied from them.. certainly not the best design layout.. [/QUOTE]
