Hello,

for our company, we just purchased an industrial CNC machine built in China. We had it built for 220 volts, 2 phase, as we were told that is what we have in our warehouse. Now, when we got it and adjusted all the plugs to fit US sockets, we found out the the voltage in the sockets are from 242v - 249v (mostly in the evening). We contacted the manufacturer and he confirmed that machine should not have problems with 240 volts, but it would be better to keep it lower than that. So 249v might be a big problem for us.

Is there some easy transformer solution to step down from 240-250 to 220 volts?

Thank you very much, please be aware that I do not know much about electricity, volts amps etc :))

If you go to your nearest supply house they should have your transformer. Right next to the Romex stretchers.

OR you can just hire a qualified 'lectrictian.

Run a microwave in series between the machine and the power source. Not only will it drop the voltage a bit but your hot dogs will cook faster.
