BUMP!! Still waiting!
These are all recent inspection with newer panels installed. I have dozens of pictures.
Those guys do some ugly work not to mention full of violations.
Thanks Frank. Looking at the 3rd picture it looks like the neutrals and grounds are on the same bus bar. That suggests a bonded primary main service panel. That said, the disconnect is still external. Right?

We see this often in Florida, an exterior electrical disconnect panel with the interior panel wired as a main panel.
From here your first two photos look like they were wired as a remote distribution/subpanel
the disconnect is still external. Right?
All the systems had external disconnect panels at the meter.
So…external disconnects at what many consider a main service panel yet the service panel shown (third picture) is bonded as a main service panel and not a sub-panel.
As one reviewer recently stated, don’t assume anything, look close and don’t make assumptions.

Both of those panels have issues…
The first one looks like the bonding screw is backed out, which would be correct, but why does it have 2 different EGCs with the feeders? One of which is solid copper…
The second photo has a4 wire feed, but doesn’t have the neutrals and grounds separated, and is missing the bonding screw… so it’s wrong either way…(whether it was intended to be a sub or a main)
I’ll just add to this thread, remember that if this is new construction and the exterior disconnect is labeled as the “emergency disconnect,” it might not be the “service disconnect.”

My guess is that the bare copper conductor run with the feeder is a GEC.
Anything downstream from the main panel in the same structure should have grounds and neutrals isolated
That is a false statement.

Hard to tell, but it looks like one goes to the right grounding bus, and one to the left grounding bus.
Would that be considered parallel paths? Or does that only apply with the neutral?
And, I thought you couldn’t run a solid EGC in the raceway to a subpanel?

It does appear that each one goes to a separate EGC bus on either side of the panel. As a general rule conductors in raceways larger than #10 are required to be stranded. EGC’s are permitted to be connected in parallel as the restrictions of 310.10(G)(1) do not apply.
Thank you.

Fair enough… Yes, oversimplified. Please spell out all the (rare) exceptions that residential HIs run into so I don’t kill anyone.
27 have been identified plus one sarcastic response.

So, in one thread you’ve gone from needing to ask to knowing so much you can’t be bothered to answer? Glad we are all so helpful!
I’ve had well over 50 responses and thanked most. Inquiry was resolved well over a week ago and certainly not in one thread, perhaps 10. Got some straggler responses since then, even some demanding more information. Learning from some responses probably best just not to inquire in the first place. Hopefully this puts to bed the inquiry.

Please explain.
Are you just picking on words? (isolated), or is there something else to that statement?
Thanks
Thank you Daniel.
