Most (all??) homes in the US are 220 volt mains with each branch 
being the 110 (117?) volt service.  I had similar problems and
solved them with a low value (very low value) capacitor (around
.01 mf) across the 220 main (not the ground connection)  don't
do this with the power on (ie. do it after the main breaker, pull
the fuses or breaker physically out if you can easily) and still
act as if the circuit were live.  (Many urban legends exist about
false paths for the power when it should have been off.  Try not 
to become a legend in your own time ...)
