I am just about to wire the distribution box, see pic below and drawing below, This distributes the incoming power from the meter panel next to it out to the garden room 1x80A fused unit (upper), the main house - 1x80A fused unit and a local commando socket (16A) and the garden lighting (1x small CU 16A / 6A breakers). I have three things I am not sure of so any ideas greatly appreciated; Should I use ferrules on the ends of all the 10 / 16 and 25mm2 tails across the cabinet (they are already on the internal wiring in the small CU). I would have though I would but installations I have seen don't always use them and the regs look agnostic (526.9.1 in 17th Ed)! To get the cables in and out of the CU I propose to just use simple grommets around the holes, I don't think I need to seal them although I could. Do I need to earth the earth connections, and run the earths through, on the Switch Fuse units as the earth common block will be used to terminate the earths from the cables these supply, it seems daft to introduce two additional points of failure by connecting the outgoing cable earths via the switch fuse units. The cables will all be held down on the board by cable ties through table tie plugs in the board. All and any thoughts appreciated.
