@joth the central hub distribution board you build (amazing work) looks exactly the same principle I am planning to build next year, when our house will be rewired and new consumer unit installed. I've read and compared the wired based intergation systems but failed to find any schematic(wiring diagram) examples for the distribution panel.
Did you draw up drawings before you started your construction? or did you have sameone else do them?
Any help of examples would be much appreciated, or direct me in the write direction.
