It is well within the range of these 'taps' to set them at 460- just ask the guy to do it when he hooks it up.

The "guy" hooking it up is me and whenever I ask him something I get weird looks from other people [Linked Image]

Is there not a manual or a spec sheet for the machine with a min and max voltage range? Since the machine includes electronic equipment, I would expect such a specification.

No Manual as of yet, just a request fron "the boss" to size a transformer for a 60 amp 460 volt machine.

A 460V motor is intended to be run on a 480V nominal system.

I do understand this,I was mostly looking for a little reassurance after being questioned by a fellow electrician, always like to make sure I didn't miss something.
