[SML] Sympathetic GFI Tripping

Started using our Blendtech after a hiatus and since the kitchen renovation.

Part of the renovation added two circuits with GFI breakers in our 
electrical box.   Well, it seems when the Blendtech kicks in to high 
speed there must be an induction of current into another circuit as one 
of the new GFI breakers trips.  Not the one with the blender on it, but 
another one!    Am guessing the wires are running in parallel to tightly 
packed going through holes in the floor joists.

And it doesn't happen every time the blender kicks into high, only if it 
had something heavy to blend.  Filling the jar with water won't produce 
the sympathetic tripping.

The circuit being tripped isn't in the kitchen but runs the lights and 
outlets in the breakfast area, so I'm replacing it with a non-GFI one.
