I wondered about the best approach and where GFCI should be used in the shop.
A couple of options
- One or more GFCI breakers in your single phase panel
- A GFCI outlet in each 120V circuit.
So basically, the 240 3phase to power the lathe motor, but we're just going to do a separate circuit altogether for controls/accessories. That actually makes good sense. Does this mean I'll need like a "master power on/off" for the 120v control circuits?
If you plug it into an outlet, a master switch is not really needed. The way I do it on my lathe is the E-stop switch serves as the ''master''. On my mill, I do have a master switch for the 120V power, but it's not really needed since it plugs into the wall. The switch was in the panel when I got the mill and would require actual effort to remove it.
Speaking of wall receptacles for 120V, buy the good ones, 20 Amp, industrial or heavy duty. They are about $5 each vs. the $0.95 ones, well worth the price difference in the long run.
That would be difficult to install.I just wasn't understanding where.,. If my 3 phase is in one panel, my single phase in another...
