Nope.Did the separate structure have its own grounding electrode too? If so then that's fine.

I see that there's an exception (at least in an older NEC, not sure of it has been removed since then) for the grounding electrode requirement for a building that only has a "single branch circuit". None of my structures fit that requirement so they all have their own grounding electrode.Nope.
You have multiple branch circuits from the main in your buildings?I see that there's an exception (at least in an older NEC, not sure of it has been removed since then) for the grounding electrode requirement for a building that only has a "single branch circuit".

All of my subpanels have multiple circuits. I think that exclusion is there for situations like running power to a shed just to run a light or two.You have multiple branch circuits from the main in your buildings?
I have a 200 amp service running to a 30x50 shop plus I have a barn with 100 amp service.All of my subpanels have multiple circuits. I think that exclusion is there for situations like running power to a shed just to run a light or two.
That barn absolutely needs a grounding rod. That would never pass inspection here.I have a 200 amp service running to a 30x50 shop plus I have a barn with 100 amp service.
No grounding rod.
All runs back to main house and grounded there.
Passed here.That barn absolutely needs a grounding rod. That would never pass inspection here.
It must not be a common situation where you live. Where I'm at it's very common so the local electricians and inspectors are familiar with the code. Just on my property we have 4 main panels and about half a dozen subpanels that are all in separate structures.Passed here.
Have never seen a grounding rod away from main feed.
We also have sub panels in detached structures just no Grounding rods.It must not be a common situation where you live.

We have two meters. Each one feeds two main panels.We also have sub panels in detached structures just no Grounding rods.
They pull the ground/neutral bonding screw from sub panels and everything goes back to the main.
Not sure why you would need multiple main panels. You only have 1 meter yes?
That’s either a big ass farm or a commercial structure.We have two meters. Each one feeds two main panels.
You're right it's a farm. One meter for business use and one for "personal". 10 different structures.That’s either a big ass farm or a commercial structure.
I have never seen a home with multiple feeds from a transformer.

That makes more sense.You're right it's a farm. One meter for business use and one for "personal". 10 different structures.
Electricity doesn’t take the easiest path to ground. It takes the easiest path back to the source to complete the circuit. Lightning takes the easiest path to ground (earth).No one is getting shocked by an electrical system because they walked into an area between 2 rods that were properly grounded. Electricity takes the easiest path to ground. If you're not it, you're not getting shocked.
You are more likely to get shocked by a poorly grounded system . A bad connection between the egc and the rod can get people hurt.
Electricity will take the easiest path to ground. If that path is the grounding conductor fine , if it a short or direct path to ground that's another. Taking the easiest path to ground and tripping the breaker or fuse are 2 different things.Electricity doesn’t take the easiest path to ground. It takes the easiest path back to the source to complete the circuit. Lightning takes the easiest path to ground (earth).
Ground and neutral can only be bonded once, at the first disconnect at the service entrance, typically the main panel. They are bonded specifically to give ground faults (leaking current) an easy path back to the source neutral, which creates a “short” that will trip the over current protection device and “clear the fault.”
Electricity will always take the easiest path to complete the circuit. For utility power at a residence the transformer just before the service entrance is the source. In order for current to flow a circuit must be created either between either ends of the winding to the center tapped neutral or together (split phase is 240v L1-L2 or 120 L-N). Unless this circuit is created current won’t flow. Even ground faults are only using earth as a means for current to flow back to the transformer as the center tapped neutral is also bonded to earth ground for lightning protection, however there’s usually enough resistance through earth that not enough current would flow to trip the breaker causing an electrocution hazard. Only lightning is specifically trying to get to the earth. Per NEC the grounding conductor is meant to allow a path back to the source, not earth which is the entire reason for the ground/neutral bond in the main panel as the neutral is what completes the circuit. “Grounding” rods are there to give an easy path for lightning to exit the electrical system. This is also why each structure requires its own grounding rod.Electricity will take the easiest path to ground. If that path is the grounding conductor fine , if it a short or direct path to ground that's another. Taking the easiest path to ground and tripping the breaker or fuse are 2 different things.
