Out of the blue, my faithfull old Hoover washer tripped the RCD on my consumer unit.

Mains tester plugs like this one

have some leakage from live and neutral to earth
so can be used to trip RCDs which are almost tripping
which could be useful in finding whats going on.

But I dont know how many milliamps they leak, anyone know?
