So I'm probably buying a used Fadal mill. It is currently wired for
480 volts. The shop it is in uses an inverter to convert the incoming 240 single phase to 3 phase which is then sent to a step up xmfr and then to the mill. The RPC maker is no longer in business so I can't ask them if the RPC I have can be connected to the xmfr. Can this be done? I think I can re-configure the mill to run on 240 volts but I'm not sure. Furthermore, there are already wires in my shop that can supply power to the Fadal but I think the gauge might be too small for the amperage draw if the Fadal is wired for 240. Adding wire would be kind of a pain as I would need to pull wire through about 40 feet of conduit. I can do it but it's a pain plus I would need to buy 180 feet of wire because the machine is 3 phase and there is another 15 feet of wireway the wire needs to go in. The wireway is the kind where you just remove the covers and lay the wire in. The conduit goes from the wireway up the wall 18 feet up, across the building, and then down the wall to the wireway on the opposite wall. Thanks, Eric- posted
