(I didn't actually understand it until taking a engineering course) So to you it might be a 'hair' but I have seen people walking around confused for YEARS because of it. I think it is actually easier to explain it as a 240 volt transformer that is center tapped for neutral from the start. Now it is intuitive as to why it is single phase. Just MY experience though.
I see what you're driving at, and perhaps I've found it is just easier to explain it to people this way. Perhaps I am lazy on my part. However sir, you need to work on your delivery
All I got from your initial post was a quick summary enough to say, "technically you're wrong and I'll be vague enough to show you I'm right. The rest of the audience is still in the dark, never mind the fact I am bringing this up to educate them."
Something more or less like L1 to Neutral and L2 to Neutral only pick up a quarter cycle of the wave form resulting in half the amplitude when compared to L1 and L2's half cycle. Then you need to get into RMS and all that good stuff because we shouldn't confuse people that it isn't 240V peak to peak. And I am sure we can drill down to something else from there.
Any how, we're not educating electricians or engineers. If you feel you need to know that much about it then take a class. It's enough to get some one to understand the gist of it. Perhaps it frustrates you because you were taught wrong starting off in a trade when you should have been shown the right way the first time. I agree with that.
Sorry for polluting the thread Pol. I'm done talking about it.
