    70mm2 crimping terminal

    Hi all,

    I have a more general electrical question.

    We have an 100KW inverter that needs to be connected to the grid. It needs to be done with 70mm2 cables for each phase plus neutral. To do so we.need to crimp a 70mm2 crimp terminal to crimp to the cable. What if the hole of the crimping terminal is to small to get it over the connection terminal in the inverter?

    Should you use an other terminal or can you make the hole bigger by drilling with a electrical drill and make the hole bigger.

    Is it totally wrong to make the hole bigger or will it be ok?

    Curious to your answers


    Many thanks

    I am sure you can find a terminal that has the correct hole size and be used for those 70mm2 cables. Any changes to an electrical terminal may end up being rejected by the inspector.

      There is a huge variety of lugs made to cover those applications. I would
      start checking by Del City in Menomonee Falls, Wis. The soft lug material
      is hard to drill, without bending and distorting the whole thing.

      You mean, too small? Bruce Roe
