As was suggested it was the GFCI itself that was the problem when
inductive loads were switched off. I tested every GFCI receptacle in the
house and found that they all test fine using the test and reset
buttons. I found one other GFCI that would trip when the hair clippers
were turned off. I replaced one GFCI with a Leviton unit and tried to
get it to trip and it would not, no matter if it was the washer or the
the clippers. None of the exterior GFCI receptacles would trip. One in
one bathroom and one in the kitchen would trip. Our basement has high
humidity, which I am working on to eliminate. The bathroom gets humid
too. But the kitchen does not, even when boiling big pots of water, so I
don't know if humidity has caused problems or if it is just chance.
Anyway, at 26 bucks a pop from the local hardware store it would cost a
lot to replace all the GFCIs in the house. I need to do some online
shopping.
Yes, I have had to replace several older GFCIs that were starting to get
nuisance trips. The new units worked fine. I'm guessing that the
constant assault of transients slowly deteriorates them.
