WHY, 3W Delta 480V instead of 4W Delta 480V?

[Joethemechanic]

I’ve been around hundreds of industrial machine tools, and I’ve never seen one that required 240/480. Anything that ran on 480 required only 480.

Almost everything I've dealt with had 240-480 motors on them. If anything the problem has to do more with contactors, discos, and other control circuits.

Sure I see motors with only single voltage brought out, that can kinda suck too, lots can be wrong.

But everyone I know with a mom and pop business with 208 wye, like a garage, machine shop, wood working, whatever. They always end up with lots of b/b transformers everywhere.

In PP&L land they only offer it to legacy customers anyway, so all the new services are 208, or 480

480 / 240 motors. as in 480 or 240
But not both, delta/ wye motor windings.
I am not sure I have ever seen a 480 anything that needed a neutral?
I have seen lots of 277V lighting.

Correct. Most machines could be ordered in either voltage. When built for 240V, the motor controls, wiring, and disconnects had to be upsized accordingly. Control voltage (120V) supplied by integral transformer.
