For as precise as electrical work is I've always been surprised by the variations in voltage listings. I know three, 110V, 115V, 120V. All the same thing. Also know 220V and 240V. What the??????
Modern systems in the U.S. are 120/240. There are likely some old industrial areas that are 115/230. Iirc, 220/110 was the old 2 phase system that's been obsolete for 60+ years.

Some foreign systems are 110/220 50hz so you may see some modern devices labeled that way.

I think you and I grew up on 110 volts, now voltage has increased to 120 volt, someone change their mind somewhere along the line.

Thank you. What's odd to me is that is says A.C.-D.C..

That's not odd, what's odd is I didn't notice that till you brought it up, I had to go back and look at that tag again. I think the suspect was wearing a blue hat, checked shirt, blue jeans, high heels and driving a kabota B6100 :pinkpanther:........

Does the voltage new and old have to do with delta and wye transformer wiring?

I know there are a lot of old ways of doing three phase that people don't generally use anymore. One of them being the old 3 phase with a high leg.

Odd to me, I've never seen someone go from AC then move the cord to DC. Blue jeans and b6100 is accurate enough, is kabota a Chinese knockoff? :D

At the Hospital all the regular outlets come in at 124.5 volts... it was designed this way...

Up at the cabin the voltage is sometimes 108 volts.

Delta and Wye generally only effect 3 phase systems. On 240v systems where there is delta transformer you have 240 between any 2 passes but if it's got 120v you only have 120v from 2 legs to ground the third leg is a high leg and not used to ground. Wye systems you have 120v to ground on all legs but phase to phase is only 208v.

Often Wye systems are used for commercial services where you have a lot of 120v loads and delta is used in industrial facilities where you have more 240v loads.
