[R-390] line filter for EAC R390A

[rbethman]

Dick,

GFIs "see" current in the ground as a "fault" above the limit that a 
GFCI "can" allow.  So the saying that the grounding through the "third" 
or "green"/"bare" IS what is popping the GFI.

An R-390a with the old filters will stay on when it happens to NOT be on 
a circuit protected by GFI devices.
