That is definitely NOT college level electrical engineering. Looks
like a junior college introduction course to me.



I won't go into a discussion of how facts at a junior college are any
different than facts at a high school or university, or even those same
facts at the power company (the references I cited were from industry also),
simply because, I'll lose any argument like that on the net due to the
old adage...

And, I'll stop asking for references that state the currents *don't* go
back to the power company transformers through the ground...

I will simply continue to locate, read, and quote sources that explain the
return path for current, back to the power company's transformers.

The more I read, the more I find that this return path is not
straightforward.

There are local loops, where the math can get complex, so, I'm trying to
unwind this wye-versus-delta thing as we speak ...

Here's a good starter paper on what those ground paths back to the power
supply transformers looks like that I am still reading with great interest:

That's from a company that makes isolation transformers, so, they're not
"junior college" level, right?
