Hello,
I just bought an old Unisaw that appeared to be wired for 220v, but the way it was wired was extremely confusing to me. At the switch, there are two wire coming out the top feeding the motor, one black, one white. In the bottom of the switch coming from the power cord are a black wire and a green wire, both hooked to the switch. There is a white wire hooked to the metal switch case, where ordinarily I would think the ground would go. The power cord is 10/4. The red wire is not utilized in the switch box, but is connected in the plug to a hot lead. The green wire is hanging loose at the plug. Black wire is connected to hot. White wire connected to neutral. It is an old fashioned 3 prong dryer plug. The cord was very damaged and frayed, but the saw turned on when plugged in. To me, it must've only been getting 120v in this configuration, but the plate on the motor shows this setup. Help!
