I'd say a problem with 312.5(C) as the cables are not secured to the cabinet. Also, has derating been considered per 376.22.

I agree with this.

312.5(C) Cables.
where cable is used, each cable shall be secured to the cabinet, cutout box, or meter socket enclosure.

There is the exception to this section, and there are multiple conditions of which "ALL of the following conditions are met"

I do not see all of the conditions listed in the exception as being followe.
Also it was mentioned about the bonding of the trough, or the lack of bonding of the trough.

Otherwise, it is a clever attempt at trying to install an aesthetic method for NM cable.

My first (insane) thought was that he used steel nipples inside of PVC couplers (for looks :-?)

Upon closer inspection I'm fairly certain that he used threaded adapters glued back to back. (you can see solvent drips in the first picture) I can't even be sure if there are locknuts below those bushings.

Here's how I envision this conversation:

"Grounding? Whatcha talkin' about Willis?"

I enlarged the images, and it does appear there are locknuts. But locknuts alone won't bond it anyway. And PVC isn't going to bond it not no way, not no how.

So unless there's something that's not visible in the images, thats a big 250.4(A)(3) violation.

Good to hear from you, Pierre. Glad to know you are not out of reach, and can type again.

Anyway, I have concerns on how he routed the wires out of the panels, into a cable tray, and out of the back of the cable tray - clustered wires, not clamping, etc.

Where is the cable tray behind the plywood?
 
I'm ASSuming that the panel shown is a sub. I think I see a bonding jumper still installed from neutral to the ground. It's going to be tough to bushing the back of the gutter without tearing everything apart. :rolleyes: I use gutters occasionally on resi's but IMO those pics don't look "neat".

On the outside, 3 meters, with outside main disconnects, are present - one for each apartment and one for the "house" on this side of the building (a mirrored image is on the other side - this is a 4-fam. home).

The SEC (?) runs from the main breakers through the walls to the panels (there are 3) on the inside of the garage.

I think I got the terms incorrect - the metal housing above the panels is called a "gutter"? Sorry for my naivete.

do they make medication for that ??:D
