That Intermatic unit has a white wire, does that mean it requires a neutral? (the installation manual on the page linked doesn't say).
That would be a show stopper in most 240v installations since they probably did not bring a neutral to the pole.
I am still not sure why the 2 wire PC in the top note is not acceptable (assuming it is listed to open a 240v circuit). A photocell is not a disconnect and should never be confused with one.
