This is the picture I was referring to.

While I am waiting for my VFD and spindle to arrive. I need to run a cable and install an outlet for the 220.
That won't be so bad since the breaker box is nearby.
The power cord that goes to the spindle I have now is rated at 10 amps. Thats 20% higher than the specified current for the new spindle (8 amps.) It is 16 Ga., 4 wires, 300VAC. Do you think that is ok?
Thanks again.
Charles
Please correct me if I am wrong. Is there an issue with running the VFD from a 220v outlet and everything else that is 110v (PC, Controller) going to a different outlet that my or may not share one of the 220v 'sides'?
Should I run 220v to a box or enclosure and break out the 110v and 220v from there?
Thanks
Charles
It has to be a shielded cable and Quality 16gauge is fine, only if it is shielded and with a high flex rating, the code requirement is 125%
This is the cable that I recommend for the VFD to the Spindle CF6-15-04 there are other manufactures with similar cable https://www.igus.com/search?q=CF6-15-04

I'm a McMaster type of guy. This specs the same.

Ok, both the VFD and spindle arrived today. YAY!
When you get the time, can you please send me the VFD parms that I need to set to keep from damaging this equipment?
Thanks again for all the help/advice.
Charles
This should be all you need

How does this sound?
Even though my CNC is 15 ft away from the breaker panel, I would like a main shut off for everything (except PC).
That means the
VFD
Smoothstepper wall-wart power supply
and 48v 12.5 A power supply would all be fed from the same 220v box (sub panel? I don't know what its called).
The subpanel would be fed with a cable that can handle 30 amps (10/3) or 40 amps (8/3).
I don't have to enclose all the electronics in a $100+ enclosure/box do I?
If I don't need a box for everything, then can I use something like a Square D 30-Amp Fusible Metallic Disconnect?
https://www.schneider-electric.us/en...-30a-2p-nema1/
Then, from the box breakout a 4 Gang 110v outlet and 1 220v outlet. Using conduit between the outlet boxes to keep it nice looking.
If all this above is nonsense, do you have a link to a diagram or picture of an install I can follow?
Thanks
Charles
You really should have a Box to put everything in, but a lot do have the VFD outside
From your main panel you would have to use a 4 wire cable not 3 as you have suggested using 10/3, you need a 4wire cable to be able to do 120v and 240v from the same supply you need a Neutral and a Ground
So from the main panel you would wire to a disconnect from the disconnect you would use a 2 Pole Breaker for the 240v and a single Pole Breaker for the 120v supply, these would need to be correctly mounted in a box along with everything else that you can fit in it for your machine
You mount every thing on a metal plate and this plate is Grounded with a ( star point Stud or Bus ) The metal Plate is called a Ground Plane
The 240v supply Voltage is wired / connected to the Disconnect Just the 2 Hot wires in your case most Disconnects are 3Pole but you only use 2 of the Poles for switching
Here is a disconnect and the Breakers you would use they don't have to be the same as this but they will be of a similar type

A few more questions:
1. Do I need an EMI filter for the VFD supply?
2. Which should I use relays or contactors, that are also controlled by my E-stop switch, to turn off the VFD, Cooling pump, Stepper motor controller?
Thanks,
Charles
Didn't realize how expensive enclosures could be.
Saw this steel tool cabinet at a store nearby.
Its 28" x 28" x 12" for $80.00 Not very dustproof since there are no seals, but that's an easy fix.
The shelf is removable.
Would that suffice?
Thanks,
Charles
