“Panel is flat on board. Now, I normally”

Please read my exact quote above.
Pleasure meeting you.

Questioning @rmeier2 lost any creditability I can conceive from your post.

Sure. Let’s look at the pic.

Panel is flat on board. Now, I normally would not comment on a mock-up, educational unit but we are in this deep.

If installed indoors real life:

1. This is a flush-mount panel, evidenced by the 6 drill holes along the front sides. Installing as pictured is a code violation.
2. Exposed Romex entering at the sides is a violation, at the very least, of 110.12.
3. Where is the premise wire grounding?

1. The same holes are used to secure the cover whether flush or surface mount. Where is the violation?
2. Exposed NM is not a violation.

110.12(C) Cables and Conductors. Cables and conductors installed exposed on the surfaces of ceilings and sidewalls shall be supported by the building structure in such a manner that the cables and conductors will not be damaged by normal building use. Such cables and conductors shall be secured by hardware including straps, staples, cable ties, hangers, or similar fittings designed and installed so as not to damage the cable. The installation shall also conform with 300.4 and 300.11. Nonmetallic cable ties and other nonmetallic cable accessories used to secure and support cables in other spaces used for environmental air (plenums) shall be listed as having low smoke and heat release properties.

The next section in the article has remained unchanged for more than 50 years. In accordance with 110.12, electrical equipment shall be installed in a neat and workmanlike manner.

Hard to say it would fail is in this aspect.

Section 336-6 permits NM cable to be installed in exposed locations and has permitted this installation technique since the introduction of NM cable into the Code in the 1930s. If installed exposed, the cable must closely follow the building surface or be installed on running boards. The NM cable must also not be installed in an area where the cable may be damaged or subjected to any physical abuse that might affect the safe operation of the system.

You are not an Electrician. Please let it go.

Seriously? You are one weird character.

It is up to the local authority what to require. The NEC only says that work be neat and workman-like and that equipment be firmly attached to the surface to which it is mounted. It’s generally understood that it’s impossible to firmly mount anything to drywall, thus a more substantial surface is required. What that is is up to the local authority.
Haven’t you heard of fire-resistive paints?

And the neat and workman-like is too vague to be enforceable.

[wbernauer (Walter Bernauer, CMI®)]

Hell I thought Robert Meier rmeier2 wrote the codes. I suppose you might have issue with this? LOL!

[mcyr (Marcel Cyr, CMI)]

I swear these WAFI’s are coming out of the closets lately. Who is teaching these guys?

[jmilby (Jim Milby)]

Maybe that guy from Ohio?

I appreciate your work in supporting facts. My experience in this area comes from 25 years of civil, utility, industrial, commercial and residential installations.

1. We will pretend that this famed panel is outside. Few see a problem with its installation, which is OK.
   I see an ungrounded metal box with energized components sticking out approximately 8" in the open air, waiting for the sprinkler system, rain and lightning.

2. The Code Book gives rules in regards to protection of life and property. It is not a How To book for electrical construction.
   For Example: You are correct that Romex (NM/NMC) can be ran exposed, however, the installation of good workmanship does not interpret it that way. Again, Romex can be ran plenum, which is exposed, BUT in the walls, ceiling or attics of homes. It does not need a raceway in these areas.
   It is, however, below workmanship to run Romex along walls like Christmas garland.
   All who is reading this may have Romex exposed INSIDE of their walls, but hopefully no one has it visibly EXPOSED running from receptacle to receptacle, to electrical panel.
   This is why I called out the Romex running to the sides of the panel.

[gparker5 (Gary Parker)]

No more Online Harrassment from you.

[jmilby (Jim Milby)]

Why is an exterior panel even being considered?

Again, workmanship is subjective and unenforceable. NM shown closely follows the building surface and meets the criteria of the code rule, not some entirely arbitrary opinion.

Grounding may have been at the meter and provided by metallic conduit.

@gparker5

No ground bar or evidence of #6 ground rod (clearly not a 100A panel) and supplemental ground?

@gparker5

I see an ungrounded metal box

It is obvious that this panel is set up as a distribution panel, with grounding, and a back fed breaker. An inspector would have caught that…
This topic has gone way off thread, and frankly pointless

Workmanship is enforceable by AHJ and electrical contractor.
