Voltage conversion question

[Pink12345]

Hello. So I have some equipment listed as 240V 3PH 60Hz 89A. My issue is getting that amperage to the equipment. Would something like a 480V 3PH line (50A) and a transformer (480V to 240V) to the machine work? Or would the machine need to be entirely retrofitted to 480V?

It is quite common in industrial settings to feed 480V to a location where lower voltage is needed, and then to step the voltage down to the local requirements.

But you need to have the necessary service capacity in the first place.

Your electrician should be able to determine the available service capacity, and then size an appropriate transformer for the load.

Sounds good if ampacity works out. We recommend a delta/wye unit for easiest secondary grounding.

Thank you for the help!

How would you get 240 with a wye secondary? 240Y/139 volt secondary?

Absolutely, like often used to suit VFDs.
