Many commercial ovens are 480v. Hobart and Vulcan have these available. Also many commercial walk-in freezers are 480v.
And 480v is somewhat the commercial standard for electric motors as well.
The 480v rating is not unusual for commercial sites and is usually available for installation by your power company.
