Is the resistance 1 Mohm (= 1,000,000 ohm as you say in the first pos)t.
Or is it 1 kOhm = 1,000 ohms that you use in the calculation?

If it truly is 1 Mohm, then the leakage current would be 1.5 MICROamps = 0.0015 mA, which I am betting is within safety limits.

Tim, it's 1k. This is the circuit used to make the measurement. It's supposed to simulate the human body's impedance.

I made a mistake, It's 1Kohm.(I fixed it)

I've finally found a proof in standard for all the discussion above that the test is unnecessary.
See paragraph 16- ENCLOUSERS and PROTECTIVE COVERS in
subclause e-1.
This says that an access to LIVE parts is allowed if the the voltage not exceeding 60v DC. (Even in Normal use)

Thanks
