110v Light Wiring On 220v 3phase Lathe?

How about using low voltage LED lighting from a transformer that can be fed 220v.

While I'd really like to learn the LED / transformer thing.
It'd take huge patience from your gals/guys to teach me how this works.
While LEDs last nearly forever and would likely never need replacing, does the expense of the transformers offset the savings?
Where do you get the transformers?

You got it now. Your easy answer for 110 circuits on a machine with no neutral leg coming in is going to be to pull a 12/2 with ground wire on its own breaker. If your wiring to the rpc isn't pulled yet, you could also pull a four wire lead to it and split your hot, neutral, and ground to create 110 before it goes into rpc. I think your separate 110 circuit from the box will come out cheaper. Good luck

While my 20hp RPC is several years in place at this point, I'm thinking of relocating it this summer. Perhaps someplace where I won't hear it...
I apologize but I don't understand what this means "If your wiring to the rpc isn't pulled yet, you could also pull a four wire lead to it and split your hot, neutral, and ground to create 110 before it goes into rpc."

Are you willing to very patiently expound?
Please.

Thank you,'

What LEEQ was thinking, that if you have not fed wire to the RPC from the panel, you can use a 4 conductor - 2 for the 220 volt, 1 for the Neutral ( This will give you a 110 with 1 of the 220) and a Ground wire. After the 3 phase leaves the RPC, you will have the 3 phases and the capability of 110 as a separate line thus solving the 110 problem and having to worry about running at RPC just to have the 110 when 3 phase is not needed. This is on the assumption that you are using 220 to run the RPC. No extra fuses/breakers required as the 220 already has them at the panel.

Since you mention that you may be moving the RPC, this could be one way to do the job.
I hope I did not misinterpret what LEEQ was thinking.

Hmmm.
Does this require a special socket?

You could use a regular light such as a flex arm. 220v bulbs are available in medium base. I would recommend a 2 pole switch ahead of the light so that the shell of the lamp is also turn off. If you are looking to put a light over the lathe most new fluorescent ballasts are universal voltage 90-277v.
The transformer, if properly sized, would give you the option of adding a receptacle for small loads at the lathe. Probably be more than you want to spend though.
 
Might be worth using an isolating transformer to increase safety, or are the lights waterproof/damage proof ?

Or as somone else said use a transformer for low voltage light e.g. 24 volt.

You should be able to get a lot of lamp bases in a range of voltages, es lamps are the most common fitting I see in many different voltages.

That's about it. They sell heavy gauge wire with three conductors and a ground. A red, a black, a white, and a bare wire. That's two hot legs, a neutral, and a ground. Some 220v devices run off of 220v, but have 110v controls or features. This kind of device requires that neutral leg. If that were run to the rpc, you could split off 110v from there and run it the rest of the way to the machine. Clear as mud, right? Now knowing you might relocate your converter, I would suggest just pulling a new 110v circuit over to the machine. You would be able to power more than just a light with it , too.
