Anyone use the Progressive hardwire surge?? not showing amps

You should see an amp usage all the time. Mine is typically 1 to 2 amps because of the radio,CO detectors and such. If you turn on the Ac or microwave you should see a big jump. Do you get any error codes? Yes the round core should have the black wire passing through it and be connected on the positive feed in wire. Reseat connections on the green circuit board if you already haven't done. You can call directly to progressive industries. They have a great help desk.
