Hi, I am in the thick of studying the 2330 L2 and I am curious to understand fully the diagram within Appendix 15.
Generally I am quite happy with what is illustrated however just want to confirm my understanding of Fused Connection Units and associated rules on an A1 Ring Final Circuit.
Am I right in thinking I can use a 13 Amp FCU to supply a radial circuit of a reasonable amount of sockets, providing I take into account diversity, voltage drop, R1 + R2, Zs etc.
If this is the case is it permissible taking design factors into consideration to come out of the back of final socket on the Radial and Fuse down to a 6A FCU to provide a light (Basically the whole idea being that the radial is a circuit that will provide a small amount power when needed / switched on at the 13A FCU to a separate outbuilding)
