220 and 110
220 and 110
(OP)
I currently have a machine that runs on 110 VAC. The problem is that it is going to pull too many Amps, so I am thinking of running it on 220 VAC. All of the conponents can run on 220 VAC with the exception of the Stepper moter drivers. I would like to know if there is any way to run 110 VAC out of the 220 that I will be bringing into the box? I realize that one of the legs of the 220 is 110 but I don't know where to get the ground and neutral at that point.
Thank you for any help you can offer.

Should I be taking the same amount from each hot leg or can I just take it from the one?

How many amps @110vac do you need to supply to the motors. Also, how many amps does the whole machine require when using only 110 VAC.
RE: 220 and 110
You need to be careful and identify all the components inside your machine, then evaluate each one for its 110 vs 220 operation. For example if you have a “universal” power supply rated 85-250vac, then it’s ok, but if you have a resistive load (heater?), or a motor, you will not benefit from reduced current or power (unless of course each of those components can be 110/220 switched.
Would be helpful if you clarify your load types.
