The figures have been pointed out elsewhere - it's effectively the
thick end of 10 watts needed to trip an RCD. That is a lot of heat to
dissipate unnecessarily from a power supply which would add to its
cost. And such high current resistors ain't cheap compared to what's
used - as well as bulky.


Shouldn't that be "10VA" - the leakage might be largely reactive, and
probably will with things that employ mains conditioning filters.

There are all sorts of ways - but many SMPS do use just simple resistors.

Just a thought.
