Re: CNC Spindle motor power wire type and sheilding from other wires?
Typically you would use a 230/120v 1ph transformer connected across two phases.
Also customary is to ground one side of the TFR secondary right at the transformer, connect it to the service ground, a second conductor connected to the same point will be the neutral.
See PDF 1T.
Fuse both primaries, fuse hot secondary only.
