The CONTROLLERS just need 120VAC to operate which can be obtained
from either side of the 220VAC line. I am told that some people experience
difficulty in controlling modules that are on the other side of the 220
circuit (modules not on same side as controller).
Someone posted a note awhile back on how to bridge the signals
across from one side to the other, but I cant seem to find it now.

The MODULES are sold in a 220VAC variety but not by Sears
or RS. Heathkit, Fordham Radio and Leviton all offer 220VAC modules.
They are around $30 and control up to 20 amps. Leviton (electrical suppliers)
have a large menu of "specialty items" for use with the BSR X10 system
but they are high priced.
If you need addresses for the above, email me and I will send them.

As far as schematics go, you can probably get them from RS if you
order their Service Manuals for each of the devices you are 
interested in.
