I figured out my problem and can now wake the neighbors easily with my Stebel running through the PDM60. I had mis-wired the main connector (mine is the earlier version). I had the red wire (Circuit #4 - 15 amps) stuck in the hole for Circuit #3, which is only 5 amps!! So - I was just repeating my previous failure of trying to get 20 amps by combining a 5 and a 15: Andre-Marie Ampere will simply not allow this to work. I now have Circuits #1 and #4 properly tied together allowing two 15-amp circuits to feed a 17-20 amp load. All is good.
It also confirms Rowe's decision to eliminate the connector altogether: customer failure mode avoidance!!!
The PDM60 is the way to go - assuming you can follow directions!
