I had planned to use X10 in a house we just purchased. But I found out that the house has two separate 240 volt 200amp power lines coming from the pole. One circuit feeds a bedroom wing and the other feeds the rest of the house. Each wing is about 2000 square feet. I know I can couple both phases of a single 240 volt line. But is there any way to couple/bridge the two circuits so that the X10 signal travels on the four lines?
