just givin a mid 70's BS . Now for the bad news, I onlys have two line running to the shop in the basement and both are 20Amp 12-2 wire. My new saw comes with a 10 gauge 220 line . Here is where I need help. I have my apartment upstairs from a resturant, so the wiring has to run from the second floor to the basement. The building is around 60'x40' so the wire would run the length(60') plus down two floors. I want to add a subpanel down there which I have no problems with wiring. Just not sure what size wire I should use for such a long run. The of tools that I have, three of them including the bs will get put over to 220. I am hopeing that this upgrade will help the with the struggling tools on start up. Any ideas?
