OK... interesting response ...that fault that they created in the video was a neutral fault and these was nothing wrong with the e/l unit... that was the point.
I can only assume that you had removed the neutral conductor and maybe even the live conductor from the bottom of the "faulty" earth leakage and tried to reset by pushing the lever to the bottom and then up ...before billing the customer for a new e/l unit... other wise you could sit with a small challenge trying to explain to the customer why the new e/l unit is tripping.
