Connecting up Sockets in either office or home

Hi All,

Was wondering best way to connect power to new set of 6 13A Double Sockets would it be best to use 63A RCD and 32A MCB with 2.5mm2 cable coming from MCB to the sockets I guess would you need 2 32A MCB's to have 3 sockets connected at any one time?.Then connect 16mm2 cable from the Main Power Source to the 63A RCD.The Power source consisting of 2x 4KVa Transformers and industrial sockets 110v,230v & 400v so Welders can work on the different floor levels (ie 2 Floors & Office on Ground).Also for lighting I assume its the same set up but with 6A MCB and 1.5mm2 Cable coming from the MCB.Jimmy

    So going back to the Power Clusters themselves now there are 5 cables (L1,L2,L3,N & E) I assume from the substation to the back of the Power Cluster to give it power. What would be a typical size for these cables?

    It's difficult to say without knowing what's upstream - I doubt it's direct from the DNO's substation. It sounds like you've got single core cables, with perhaps single pole connectors - if so these can be rated anything up to several hundreds of amps (I'm thinking on the types usually used on temporary events installations). So I wouldn't like to hazard a guess really.
