Vvrinc: I think it's more a function of the huge initial draw that refrigerator/freezer compressors have when they kick in, although a fridge itself will probably be a much higher draw even when it's just running. When the fridge compressor kicks in, it probably draws about 17 amps for that first split second. I'm kind of addicted to my system so probably won't do it right now, but next time I go away on holidays I'm going to hook up two cords to the fridge and chest freezer in the basement and just leave them there until I come back. I was actually quite shocked at what even one day on the freezer and one on a large box fan did to the two cords I mentioned above which I thought were fully broken in.
