    testing earth leakage

    I now have a clamp meter to test earth leakage as advised but have since discovered there is a better but of course more expensive meter available to tes true earth leakage...Megger DCM 300E I now have one with a 40A 400A and 1000A range with a minimum resolution of .01A What is now the...

    Clamp Meter??????????
