3-Phase power help

[schotshot]

Hello all.

We are about to lease a new shop, and buy a cnc router. But, we are a bit confused about 3-phase power.

The place we are looking at has 3-phase 240 on one board, and 3-phase 277/480 on the other board.

The confusion comes from the fact that some of the machines we are looking at call for 3-phase 380, or some other voltage. Can someone explane how to overcome this problem? Or, is the 380 voltage or other voltages all taken care of by an inverter?

Thanks,

SC

If you have multiple machines like this, it would pay to install a distribution transformer, 240-380 or 480-380.
Check first if the machine(s) can be changed to 220-240, many have transformers in the machines dropping everything down to this, or most single phase in the machine is 120/240, so this would be easy, and if the 380 is for 3 phase motors, check to see if they can be reconnected for 220, many are dual voltage.
