[R-390] GFI breaker trips

[Bill Kirkland]

here is my guess:

If the filter is configured for common mode and uses what is called a Y 
capacitor configuration,
then there is a capacitor connected from the Hot AC wire to ground and from 
the Neutral AC wire to ground.  There will be a small current flowing from 
the Hot AC wire through the decoupling cap to ground and this may be what is 
tripping your Ground Fault Interrupter.

An X capacitor configuration has 1 decoupling cap that is connected between 
the Hot and Neutral wire.


Trisha: how did I do ?
