   Good point on the "pointer".  A main-panel device is the only way to go for   
   total-circuit safety.    
      
   Ground-fault devices seldom (very seldom, indeed) false-trip. Sure, they may   
   be acutely sensitive to transient issues, which the typical end-user will   
   perceive as a false-trip, but the reality is that *something* tripped it. And   
   that *something* may be    
   fatal if not understood and corrected. I  have come across several conditions   
   where an external receptacle got a salt-track from the hot to ground and   
   presented apparent nuisance-trips - but, in fact, there was a problem. One had   
   to look hard enough.    
      
   Rearming to save a freezer load of meat. Silly.
