What are the chances that an older motor on a washing machine or

have a trickle of leakage current? I'd not replace an appliance
motor just to satisfy some pesky device.

And what are the chances that over those ten years, the motor winding
insulation further degrades, and due to a problem with the EGC the
chassis becomes energized? The consensus opinion, as expressed by
the current NEC (which anyone can make a proposal to modify) is that
the safety risk is larger than the cost of retiring older machinery
with greater than 5 ma leakage current.

Safety risk? The "consensus opinion" is a large helping of b.s. Here,
try this little test. Google is famous for returning 475,000 alleged
"hits" on just about any search string. So please link me to a report
of someone who was electrocuted by a leaky motor on a home appliance,
through incidental contact with the chassis. Hell, I'll settle for
someone who was shocked seriously enough to be frightened into a
doctor visit.

Another person who can't be bothered with doing his own research even
when it's this easy, huh?

There are enough of them you can go get your own if you need to read
more. And I used Google, employing a very simple but useful search term
that probably requires an education beyond that of a 5th grader.

I'm afraid the only bs here is your attitude and possibly your ability
to comprehend simply logic.

HTH,
