Question about running power to my machine

[Jackal66]

This is about the power from my breaker box to my Hurco mill.

I will have some of the wiring on the mill 120v & some 220v ( all single phase).

My idea of combining it through the same wiring is in the following pic:



I know this will work and my concerns aren't local electrical code, but will this be ok for the machine as far as grounding and everything else?

I didn't want to run a 120v extension cord and then have the 220v on another circuit.

This way there will be (1) breaker marked "Hurco".

The reason I'm using 6-3 wire is because it is already here.

Thanks,

Normally the power is taken to the Mill enclosure and then the wiring, fusing, transformation etc is done in the enclosure.
Why are you doing it the way you show?
Is there any reason not to follow a similar practice than the original, or an adaption of of it?
I am assuming this is a retrofit?
There is nothing wrong in principal with what you suggest but I would suggest you feed the enclosure with 240 1 ph and then split off with a suitable fusing etc to the 120v 1 ph circuits etc.

Yes, it is a retrofit.

I was just showing it in basic ( layman's terms), so there would be no interpretation errors.

It has a main disconnect switch. Everything goes in there first, then in the main cabinet.

There will be a 120 volt plug inside for powering my CPU.

There are others I have seen personally that used 10-3 wire, and ran (1) leg of the 120v with the bare ground for the common.

Just checking to make sure this is acceptable before doing. It seems a lot of people's problems are from grounding, or lack there-of.

Some people think ground and common are the same.

Yes, unfortunately ground is used a bit indiscriminately to mean a any common, without a particular reference as to whether it is earth ground for example.
