    Hi

    How do I terminate a 25 mm core from a 6493x, acting as the incoming earth from a switch fuse, into a consumer unit whose earth bar only has 16mm terminals.
    TIA

    Google reducing lug.

    I'd put you a link up if I knew how :oops:

    Assuming that the CCU is metal, just crimp a lug on the cable, drill a hole in the metal CCU, clean off the paint and bolt the lug to the metal CCU.

    I had the same problem a couple of weeks ago, I split the seven strands 3 and 4 between two adjacent 16mm holes, I was considering removing the earth bar and drilling it out for the 25mm core but thought that there may not be enough meat left.
