Mine only came with one unit but was pre-wired for a second. When I installed it I discovered both were on the same leg. Before I moved it to the other leg I determined what else was on both legs. Mined needed to be moved as the rest of the high usage items were pretty well balanced. Before moving yours determine what is on both legs with particular attention to high amp items like converter, micro wave, electric side of water heater and refrigerator, plug for coffee pot, and most importantly plug for DW hair dryer and curling iron. Your progressive display will make child's work out of this task.
