I do know that a GFI for an appliance is different than a Personal Protective GFI.
Personal Protective GFIs trip in the 5 MA or so range
and Appliance GFIs trip at around 30 MA.
If you run a appliance on a Personal Protective GFI, You are Very Lucky if it Does Not Trip on occasion.
If You really want to be 100% safe, Turning OFF the Main Breaker works much better than anything...
