I am not sure if i want to connect a
capacitor directly to one of my circuit
breakers in order to resolve my
communication problem. can anyone tell me
if  I put a transformer with 220 volt
primary  voltage into a 220 volt outlet if
this will  do the same thing?

No.  It might help a tiny, tiny bit, but
not very much at all.  It would also
consume electricity (even if nothing was
connected to the secondary).  With no load,
you are basically using it as an inductor,
which is the opposite of a capacitor.

A better option would be to use a passive
coupler.  If you don't feel comfortable
opening up your breaker panel, you can get
ones that will plug into a dryer outlet.
For more information see my tutorial at:

As for vendors, you can do some searches
online, but I find Automated Outlet has
reasonable prices and they seem reputable.

Some of the commercially made couplers have
a set of isolation and tuned transformers in
them. A plain 220 transformer may or may not
couple the 120Khz X10 signals properly.
