A lot of electronics will actually have a low current line to ground

time if the RF connector is hooked to a "TV out" card in a PC.

I think a lot of inductive loads can also lead to problems with
GFCI trips. I've been reluctant to upgrade the dishwasher
circuit to GFCI (as called for in the new code) for fear that
I'll be running outside to reset breakers often.

IMO, there's still too much BFM involved in GFCI's. Despite
being "simple" (in theory), *practice* seems to yield very
different results!

The "back yard" circuit, here, still needs my attention as it
trips randomly and pretty regularly despite all the outlets
being (environmentally) "protected".

[I half suspect I'll find an insect to be the cause or something
equally unexpected!]

Information I've come across indicates that any appliance which uses water or will normally get wet shouldn't be plugged into a ground fault receptacle. It listed dish washers, refrigerators, freezers, washing machines and disposals. It didn't specifically mention sump pumps. I'd have to find it again to post a link. ^_^
