What gauge wire do I need for a sub panel, of either 60 or 100 amps, with a run of 100 feet through a conduit to the main? I have a 3hp Unisaw, 2hp planer, 1.5hp jointer, 1.5hp band saw, and a 1.5hp dust collector, all on 220 volts, along with the usual 110 volt bench top stuff. This would be a one man shop.
