Su-weet!! Pride in workmanship shows up there doesn’t it? We have one EC here in central Texas that does almost that nice of work, Austin-Stafford Electric. Anytime I see one of their stickers that has been signed by the electrician I know it’s going to be done right and look good as well.

Awesome quality of work. Wish I would run across some of that.
I like those panels tight

It must have been the apprentice ( or home owner ) who did that no sparky does work like that. Been there, done it, never this neat.

Agreed, anyone that takes that much time should be fired!

Oh if they all could be like that, what a pleasure to see. that is the funny thing about breaker boxes you never know until you get inside what you are going to find.

One problem an inspector might have with these “neat” panels.
300.34 Conductor Bending Radius.
The conductor shall not be bent to a radius less than 8 times the overall diameter for nonshielded conductors or 12 times the diameter for shielded or lead-covered conductors during or after installation.
The other one would have to do with derating conductors that are bundled together for greater than 24".

Greg,
That is exactly what my electrical inspector said when I had hime inspect the the house I built and wired, by myself. He said "this is nice, but it is too neat and your wires are bent just about too sharply" He then mentioned something about the radius of the bend and the wire w/insulation diameter determining the minimum radius to be used.
But, he did say "this is nice, but it is too neat and your wires are bent just about too sharply".
He didn't say a thing about the wires being bundled together, tho.

In the typical residential panel it is hard to get 24" bundled together but in a large commercial panel it happens. I have had to tell guys they needed to cut the tywraps on their neat bundle and open them up a little.
... or show me their derating calc.
Usually on a 240.4(D) controlled conductor, wired in THHN you can get away with 9 before you need to derate but that is not a very big bundle.
Sometime a little sloppy is better from an engineering standpoint.

now I know I have bad eyes and I can’t seem to magnify the image enough to see this but would Art . 250.119 as I can’t seem to tell if those wires going to the grounding bar are actually bare or green or green with yellow stripes…maybe it is just my eyes.
Also....heck I can't tell but is the GE tied through the actual nipple as I do not see anything attaching to the grounding terminal...and I cant tell if their is a lug and attachment at the nipple as well....bonding both panels.
Can you see it better than me Greg....I did notice they must have been running short on the neutral wire...lol....it is the only one not squared off...thehehehe

Paul I didn’t want to kick the “parallel neutral” tar baby but since I don’t see a ground electrode conductor I assume it is grounded/bonded in the meter base. That makes the zinc nipple a parallel path. Half the AHJs around here fail that. The rest don’t

lol…I hear ya Greg…we are the same way here…go 5 miles and one AHJ allows…then the other does not…

This is made up as the service disconnect so ground and neutral busses are interchangeable. The wires you see are twisted EGCs.

I am sure 300.34 is not an issue here.
That looks like a 240/120 volt panel, 300.34 only applies above 600 volts.

Derating does not apply in enclosures.
I think it looks good, I do have a question of how the NMs are entered into the panel.
Personally I think its fine but it looks like the NMs are simply coming in through a PVC MA which is not an NM connector. Technically an NEC violation.

Bob, 310.15(B)(2) doesn’t say anything about exempting “… single conductors or multiconductor cables are stacked or bundled longer than 600 mm (24 in.) without maintaining spacing and are not installed in raceways…” when it points you to table 310.15(B)(2)(a).
I suppose this is another one that will depend on your AHJ.
I told y'all before about IAEI meetings where inspectors from the same department did not agree on things.
You caught me on the 300.34. Teach me to use the CDROM search
