  • What is Leakage Current Testing Measuring, How is it

    Measuring leakage current to ground via unintentional paths to ground. Clamping neutral/phase/ground all together recognizes uneven current that means leakage at a passage or electrical panel via unintended pathways to ground. If a connection to a water pipe or other electrical connections occur, similar inequality might happen.
