$600K house with only a 200A service? That must be a pretty expensive neighborhood. Has this passed a final inspection yet? I sure don't see anything to secure the cables within 12" of the panel. Neat workmanship is getting to the point where it's non-existent in these parts.
Several of those connectors have more then two cables in them. I am not aware of any such connectors being listed for use with more than two cables. Look like a violation to me.
Sure, the cable look sloppy as they exit the insulation. Yet, I like the neat arrangement of the wires in the panel, and the tags identifying each wire.
One item that concerns me - and there is no way to tell from the picture if such is the case here - is that such homes often have a spa / hot tub / jacuzzi. As I understand these things, Romex (the wiring method used here exclusively) is not allowed for such a circuit, as the ground wire must be both full size, and insulated.
The outlet below and to the left of the panel. Am I seeing a single hot wire going through the offset nipple, and two romex coming in from the top? Is the GFI (it appears) wired in series with others, and not fed from this panel? And what is that hot doing without neutral or ground?
Let's see... 3 bundled cables... would make rated ampacity x 0.7 in my corner of the world. Not exactly knowing US ampacity tables I'd guess if that's #14 it would make for a lot of 10A and smaller breakers...
Good catch, Hemingray. While aluminum is technically allowed as a GEC, it can't get within 18" of the ground. Since it's supposed to run without splicing, how it attaches to the ground rod / ufer is anyone's guess.
You need to derate for bundling only if the 'bundle' is over two feet long. I don't think the bundles are long enough for that to be an issue.
As for the receptacle ... I think I see a neutral wire there ... it's just that most of it is out of view, behind the lip of the box.
