    Nothing worked for me with this secondary test set. Had to go "in and out" to defeat the ground fault on the trip units. Thankfully I dont see these breakers that often. There was a few Eaton reps on the job as well and they didnt even have an answer for me. Not a fan of these breakers

    How should I remove the dummy connector??

    Hello!
    I just got a secondary injection test kit for a digitrip 310+ and I just can't take out this dummy connector to make it a male one... it seems to be impossible.. it is like a one-piece plastic connector...
    Any of you have done it before?
    Thank you in advance

That is the test set that has a different card for each trip unit with a dial and a push button. If I remember correctly there is a module that you plug in line that has a button that defeats ground fault. Below is from page 7. Hope this helps.

    "Digitrip 310+
    Digitrip 310+ Circuit Breakers Test Procedure
    Setup
    Before testing, write down all settings in use so that they may be
    restored after tests are completed.
    To begin testing;
    1. Connect the Digitrip 310+ cable assembly (style 5721B14) into
    the side connector of the handheld unit. Plug the other end of
    the cable into the test port.
    Note: The test plug may be covered by a “dummy connector” used to
    protect the test plug pins during shipment. Ease the dummy connector
    off using a screw driver to expose the male test pins underneath.
    2. Position Trip/No Trip switch on cable assembly to the Trip position
    and set the Ground Fault switch to the “Off” position."

    I usually just take a pair of needle nose pliers and pull the black cover (dummy connector) straight out with no issues. If your having issues, you might have a bent pin inside.
