Re Power Clusters

Former Community Member
Former Community Member
Hi there,

Was wondering how to go about putting this together and has to whether there are better ideas.Basically trying to interconnect on different floors with one power cluster to another and at present coming into the first power cluster on the ground floor there are 5 cables each i assume of 25mm2 cables labelled (L1,L2,L3,N & E) now when these are hardwired into the first power cluster would they connect to the RCD of each of the sockets for (110v,230v and 400v) and then these goto power the breakers of the sockets.And to move onto the next Power Cluster on the first floor is a suitable sized cable then connected from the RCD of the first power cluster on the ground floor to the next power cluster on the first floor?.Please help/clarify?.Also to power up a distribution box on the ground floor for the 230v lighting circuit and the office sockets can a 16mm2 cable be hardwired from the ground floor cluster units 32A MCB for 230v socket protection for the power cluster unit.to the distribution unit contained within the office?.Please Clarify?Jimmy

    I'm not clear what these power cluster have in the way of incoming cable and isolation but I would recommend you think about maintenance and flexibility. Is there a chance that the first will need to be decommissioned and removed before the others etc?

    My suggestion would be to have a main isolator on each floor and loop the supply cables between them and run a cable from the isolator to the Power Cluster, Then, if the Power Cluster needs to go, the isolator can be opened and it is safe to remove it.

    Also, you could consider a ring main to allow you to supply No. 5 after 1, 2, 3 & 4 have gone without major rewiring.
