I don't know about the 240VAC bit. But #2 is easy. The trip
mechanism requires that the current on one leg is exactly the same as
the current on the other leg to within several mA.
If you parallel them it's likely that one might supply more current
and the other will return that current and they'll both trip, even if
there isn't a ground fault.
Back to the first question, the devices I've seen use coils and a
relay to detect the fault. the coils and relay are likely the weak
points for running at 240VAC.
Either way, I wouldn't recomend it if you want to use them for their
intended safety purpose. Get the right safety device - it's worth it.
