Hi, As sensitive as some agencies are about test instruments and calibration, using a rogue current source to do this test would seem to require some level of traceability for the instruments used? We maintain an updated list of all lab instruments and calibration affectivity as used and include this list when we submit test data (we are an in-house test lab w/COMPASS CTDP with UL/TUV as target agencies). Unless one uses a calibrated instrument to check an uncalibrated 'reference instrument' prior to use, how can it be expected to perform in a repeatable manner acceptable to the target agency?
I suppose an AC 'buzzbox' welder could be used as a current source, but these are not terribly well regulated, voltage or current-wise, and getting a repeatable setting may be difficult depending on design. Pardon me if I made a dumb noise...

I have checked by regular sources and have only found testers that goes to around 30 amps. Can anyone send me a source to purchase a Ground Bond Tester that goes up to maybe 100 amps? If such a device does not exist, can anyone give me their recommendations on how to best perform this test?
