    Just wondering what way people wire sub boards.Do you come from an mcb in the main board and if so should you feed into a main switch fuse in the sub board or what?

    an mcb or switchfuse at the main board rated for cable feeding sub-board and then an isolator or main switch at sub-board.for domestic anyhow

    i normally fit a switch anyhow assuming the supply to the sub-board is already protected at main board.i dont bother with 35 or 50 amp neozeds much as these can easily be upped to 63

    did a google and the neozed fuses have adapter rings and tools similar to the old diazed system but i'm not sure that these are being used much
