I am talking about people in the trade, not some professor who has
never touched a piece of wire.
Terms have meanings. When you have to blur the nomenclature to get
novices to understand you corrupt the meaning of the term.

In other words, you can't handle the most basic electrical engineering
principles that show electrically what that service is. It's like
denying that tissues are actually a soft paper product made from
trees and insisting that they are just Kleenex, that's all they are,
that's all they ever can be, because that's how they are commonly
referred to.




The ubiquitous AA alkaline battery is two phase as well.
If you check the battery voltage, you'll have +1.5 volts.
If you reverse the leads on a voltmeter, you'll have a negative -1.5 volt phase.


Phase only applies to sources with periodic waveforms. What you're
talking about with a DC source is polarity.

It really depends on how fast you can flip a battery over doesn't ?
See what happens when you start confusing terms.
