** Double insulated devices ( lots of them have SMPS) have only a two core
power lead with no connection to supply earth. Kinda makes earth leakage a
bit unlikely.

Forget about the printers and computer monitors.. Theyre
usually ,but not always double insulated. They cannot trip the earth
leakage detector.
Sorry, I beg to differ. Any device with an SMPS will include an RFI
filter
in the power supply, resulting in an earth leakage of 2-5mA.
