AGFI is for fires. I have seen many. For example, she connected the Christmas tree. Saw a spark. In five minutes, the entire house was afire. They did not even have time to rescue any pets. That is why AGFI are required.

Another burned the entire second floor because a zip cord inside a lamp arced. In every case (and others) the AGFI would have prevented every fire.

Doug - many differences (variables) exist. For example, all appliances leak current. How much? Which one is leaking more? And which one leaks more current when humidity increases? I cannot answer you question due to woefully insufficient facts. To have an answer, you must provide numbers. And this from my previous post: newer GFCIs trip open on power loss whereas older ones did not.
