Never mind

Star grounding the easy way

Try something else, I do not see how this possibly could be a Star Grouding..
Use that link

I missed replying to this one before, I believe I was thinking of putting the star above the transformer in the diagram as that suggests a better scheme.

Please ignore this post. I realized the mistake in my initial assumptions, but couldn’t figure out a way to delete the post, so I erased it and put “never mind” because I couldn’t put nothing. That’s why the images make no sense.
