I guess you have figured by now that I am a little slow, anyway, I'm still trying.
If I bond the neutral and ground at the panel at the shed and the neutral goes bad, then any fault current will go to the ground rod into the earth and look for a way back to the transformer. This however would not trip the breaker because enough current could not flow through the ground rod, because of the resistance between the rod and earth, to trip the breaker. hence I would have a steady current flow on this bare wire and rod into the earth, is this correct?
If I do not bond the ground and neutrals in this shed panel, I would essentially have the same problem right? Because a fault would still make it to the ground through any receps or switches, again energizing the ground rod? having the fourth wire would carry the fault current back to the main panel, but would allow enough current flow through the breaker to trip it? Please don't give up on me yet, you can teach me if you're patient, please keep trying Speedy Petey and HayZee, thanks for everything so far.
