HUH?
Didn't I mention(I'm sure I did):"make sure the ground is COMPLETELY ISOLATED from the neutral"?
There it is(from my previous post):"(make sure the ground is COMPLETELY isolated from the neutral),"
Yes, you did.
Remember, electricity is seeking any and all paths back to it's source. The current flow you are measuring with your test is the flow from the one terminal of a transformer back to it's neutral, with a small portion of the earth being only one part of that path.
Read the pdf I linked to. Better yet, spend the 10 bucks and get the book. I got the book in school. It's a great book and an must have for anyone testing electrode resistance. That, and a megohmeter. I have three of them. Two battery powered (one is a real Megger) and a crank type.
The amount of current flowing through a breaker back to it's source is no indication of the amount of resistance between an electrode and the earth.
Like I said, read the book. It's far better at explaining electrode resistance than I'll ever hope to be.
