I am going to run a 220v circuit to the garage. It will have two woodworking machines running at a time, a dust collector and whatever tool I am using. The run will be about 80'counting the actual path of the wire. What size wire do I need and what size breaker?

Your breaker size will depend on your wire size--which will depend on what you are running--what are the amps rating of these tools?

Thanks Gary. I'll use your recomendation. I have #10 wire, so I'll use it instead of the #12.

Be sure to wire this panel as a subpanel, not a main, which means that you will want to separate the neutral bus from the grounding bar, and run a ground from sub to main. (If the garage is detached and there is no other common ground between the two buildings, you have alternative grounding methods). Check the Electrical forum for discussions on wiring outbuildings and grounding subpanels.
