Ah yes, for downstream recepts you'd have to go back to using a wander lead.

654,
I can't quite figure out how you envisage wiring the capacitor, but without some sort of ground reference it still wouldn't work.

A capacitor connected to AC will alternately become charged first one way then the other, giving the appearance of simply passing the AC. You could choose a capacitor which has the correct reactance at 60Hz to pass the 6mA or so of current needed, but you'd still need to reference it to ground (or pre-GFI neutral) for it to trip. And it really wouldn't have any advantage over a simple resistor.

I think you're getting at the idea of having a charged capacitor and letting it discharge into one side of the GFI to generate a pulse, right? Charging the capacitor from the recept would be easy enough (just use a rectifier diode in series), but you still couldn't discharge it through the GFI in an unbalanced way unless you have a separate reference point from somewhere else.

Nice try though! [Linked Image]
