3 phase, 380V, 50Hz motors need to operate at 3 phase, 480V, 50Hz

They didn't believe the 480V and designed for 380V and didn't ask us even though our PO clearly stated 480V. Frustrating

So.... what are they going to do to fix the problem?

Thanks so much for all of the helpful responses! We are proceeding with the transformer and have instructed the end user to increase their supply.

That is kinda weird voltage, I’ve been installing a lot of Italian equipment lately, they’re 400 volts, and the manufacturer has been supplying a multi tap transformer that works with 480, though it’s labeled 460. Their setup crew says it’s within their specs.

416/y240 @60HZ is popping up all over the place.

The issue is that the power supply at the site is 3 phase 480V, 50Hz.

jking what country is this site in? Or is it a ship or generator or something? I am curious where this 480V 50hz unicorn lives.
