[Shop-talk] GFCI tripping

In my old house, I tried using a 12-volt radio power
supply plugged into a GFI outlet, and the GFI always
tripped after a minute or so. When plugged into
another GFI outlet (the same brand of GFI!) it worked
fine.
Nothing else would trip the flaky outlet, not even a
table saw or a MIG welder. And both outlets tested OK
and I was quite sure there were no problems with the
wiring in the garage.
In my current house, there were two GFIs above a
countertop with a sink. They were probably less than
10 years old, and they had both failed: the test
button did nothing.
The moral of the story: Those GFIs can get flaky.
