Door off, the lines are in conduit and insulated in a way I can't get to them outside the cabinet. I imagine there will be more load with the door closed. I used a clamp on hall/sense current meter. Could have brought a high power sense resistor from work but figured it to be a bit overkill. In the next few years we will be house shopping at least then I can get things fixed correctly rather than the band aid fixes they usually do here.
