Coming off my transformer is a 200amp service that feeds my shop & barn, and
a 400amp service that feeds the house (2 200amp panels as mentioned below).
So if I use a coupler/repeater on one of the panels in the house I should be
ok and will get X10 across both house panels. The only leakage would be
back to my shop (as I understand it the transformer will prevent leakage
back to the neighbor) and I can easily take care of that by moving the dust
collection systems and air filters to a different house code.
