As a rule of thumb, GFI breakers are designed to trip at 5 ma. The minimum currents for death depend on what part of the body the current is flowing through, skin conduction, etc. Across the temples interfers with brain activity, across the upper chest obviously interferes with the millivolt heart impulses, across limbs and muscle damage will result. Anyone who has contacted the 48 volt battery line on a telephone will tell you it's no fun.
