I was trying to prove that the GFI was working as designed and all I wanted was for those 2 different inspectors to understand that their method of testing an ungrounded GFI ...during their respective finals... with a pocket tester was not the way to determine if the unit was functioning properly !
using wiggys, Flukes, and the kitchen sink for tests, while fun to do, are not things I want to do during final inspection(s)
As far as determining trip currents, Hubbells GFT2G adjustable tester ( which is the one I have used for decades ) incrementally increases the leakage up to 7ma, but it also requires a ground to work and would have failed to trip that particular GFI as well
