I connected my leakage current clamp to the wire to the earth wire and touched the neutral with no other wires connected ... it displays 14 mA and trips ( i do beleive this reading would be higher if the meater had a faster response time) ... which indicates that it creates a current large enough to trip the earth leakage (by the way i used a really short lead to reduce resistance) ...so back to drawing board.

I could post 2 videos of earth leakage units not tripping ... both ... the test button didnt trip the units nor did the earth leakage tester.
