Re: X-10, GFCI, outdoor lights & problems

Those are the filters I'm using.  We have different brands and sizes of
compact fluorescents on those circuits, and have no problems at all.

We also have X10 modules plugged in downstream of Leviton GFCI's, and
have had no problems with those.

As I said in an earlier post, it could be the length of your circuit.
With a switch that doesn't require a common connection, the signal path
must flow out to the load and back.  Adding the filter will place the
signal return path at that point.
