Electric question for better understanding

So I really need to tighten up my electric part and here is an example. Please call out what you see wrong to help me. Thank you


thats a very neat panel, the white wires on the double breakers should be re-identified as hot with black tape or similar.

I would guess that the NM cable connector in the upper left is not listed for 5 NM cables.

I am curious how many inspectors actually call this out? I dont usually, just because I see it ALL the time… In your opinion, how big of a safety issue is it?

What are your questions? I will assume, since you posted the second pic of just the bonding clamp, that you need help understanding when to bond, and when to separate the neutrals and grounding?

This is a distribution, or “sub” panel, because there are 4 conductors feeding the panel. Which also means there is a main disconnect somewhere before this panel. Because of this, the grounding and neutrals are to be separated, which this panel appears to be done correctly. You have the grounding conductor entering the panel, which is connected to the grounding bus bar, and this bus bar is then bonded to the panel enclosure, through that bonding clamp. On the other side, you have the neutrals on a separate bus bar, which is not bonded to the enclosure, but is connected to the neutral conductor that is entering the panel. If this was the panel with the main service disconnect, than the neutral and grounding bus bars would also be connected together, or the neutral bus bar would also have a bonding clamp.
The only other issue I see is that the neutral conductors are sharing lugs with other neutral conductors, even though there are plenty of lugs available. These should be connected individually

I wanted to thank everyone so much. Yes I wanted to double check my knowledge and ongoing learning.

If you’re referring to the 5 cables in one connector given that this panel appears to be at least a decade old IMO it’s not even worth reporting. I would wonder what would be gained by having someone open up the wall and install a few more NM cable connectors. I only mentioned it because the OP asked to point out things that are incorrect.

Yesterday a pool feed was installed inside a PVC conduit 9 inches down in the ground without any other protection, should this be reported?

That’s how I feel, it would take alot of work to correct those, and I bet at least half the panels I see have those. But usually they have the majority of cables coming down one single conduit.
