THIS INSPECTION WAS INTERESTING AS THE CONTRACTOR WORKED VERY HARD TO CREATE A GOOD IMPRESSION AS THE INSTALLATION WAS NEAT AND WITH THE EXCEPTION OF THE GROUND DOWN CONNECTOR (I DON'T BELIEVE IT WAS ELECTRICAL) WAS TO CODE. IF IN FACT THE CONTRACTOR HAD INSTALLED An EQUIPMENT GROUNDING CONDUCTOR INTO THE DISTRIBUTION PANEL SOME CONSIDERATION MAY HAVE BEEN MADE BUT REGARDLESS 110.3B STILL IS QUITE VISIBLE AS THE CONNECTING MEANS WAS GROUND FLUSH WITH THE MAIN DISCONNECT.

I am with you Redsy, However a comment. I do not like wire ties in a panel. At some point in the future there will have to be some trouble shooting done. Then you have to cut off all the damn wire ties without nicking the insulation to find where the wire goes.

Oh yeah, nice key in the panel.

If I install ty-raps for neatness, I won't cinch them too tight. This provides wire management, while allowing enough movement to trace, remove and re-install conductors.

Those square Nylon thingys with the double face tape on them are guaranteed to fall off in a week.

John,
It means that the pipe coming into the back of the box has been ground flush with the back of the panel and therefore has no locknut or grounding bushing so the conduit cannot serve as the ground(there is not a ground wire pulled in with the circuits.)He is saying that the fitting was not an electrical fitting so it did not meet the requirement of 110.3(B) Installation and Use. Listed or labeled equipment shall be installed and used in accordance with any instructions included in the listing or labeling

John,

I agree. . .I can't articulate it, but when I look at the "locknut" on the "connector", I can't make sense of what I see.

I mean, this appears to be a 1" "connector" of some sort that I've never seen before. If it's been cut or ground down, it doesn't look like it was reamed.

Then there is the proximity of what appears to be concrete screw (the blue hex head) too close to the "connector" to have adequate purchase on the edge of the hole the 'connector" is in.

I need more information to interpret what I'm seeing.

In other words, this panel ain't grounded, right?

Is this a sub-panel?

In addition to the comments above relative to nylon ties; nylon ties also make for a very sharp corner if the extra is cut off without rounding the edges:

I was confused by the round "nut/washer". I think the fitting was a set screw connector that had the barrel cut off and is being used as a conduit nipple.
