GerryAZ said:FORGET ABOUT USING A Quick220. If the place was built to Code, then the garage (and outdoor) receptacles are protected by GFCI (could be receptacle in bathroom or GFCI breaker in panelboard) which will trip immediately when attempt is made to use Quick220.
It's also just a Bad Idea. As I wrote when this product came out, I don't trust someone who builds a device that runs on dangerous house current but doesn't know that the standard voltage for it has been 240 (or 208) volts since before the turn of the century. Also, using two older circuits doubles the risk of the circuit not being up to the task.
