Hello,
The factory reference guide (page 10) for the Hitachi VFD WJ200-015SF specifies 10AWG wiring and a 30amp fuse for the single phase 240v power source. As I'm only running a 2HP 220v, 3 phase motor (PM 1340GT lathe) would 12awg wire and a 20amp fuse work and also be safe ?
The reason for asking is that my garage is already wired with 240v (20amp fuse) 12awg wire. Also found VFD cable manufactures online specify the smaller wire for that size motor. As a last resort I'll run new wiring to the garage if required.
Thank you,
Larry
