Most Violated Code Section

[hillbilly1]

Now that I'm doing a lot of residential service work, I see what my competitors were doing back when I was doing new construction

Bare grounds twisted together without nut or crimp, and/or cut very short except for the one left long to go to device

Not the worst thing I see, but the most common

Also I'm always surprised when I find a box behind exterior wall mount fixture, more common is mounting strap screwed to siding

Yeah, see that all the time over here. My neighbor built a house turnkey, it was before we had inspections, so he had me inspect it. Contractor did the same thing, twisted the wires, no greenie or crimp sleeves. He got mad when I pointed it out and told him he needed to fix it. He said “We don’t do that around here” If he is still in business, he does now! Inspector is fairly tight on compliance.

speaking of what I was speaking of, here are 2 of the many I saw today, house built in early '90s . . .

unfortunately our inspectors don't seem to notice

300.5(J), the requirement for accommodating ground movement of underground conduit runs.

I see installations where the installer clearly put an expansion fitting in the stub-up with the intent to meet this rule, but other aspects of the way that the conduit was installed, completely defeat the purpose of the expansion fitting. Like the conduit is cast directly within a slab, and can't move anyway, or that the conduit was rigidly fastened to the structure at a point below the expansion fitting, that stops the conduit from rising in to the joint to accommodate ground movement like frost heaves.

Yeah I see that all the time. I think I saw that, "non-use or mis-use of expansion couplings" on the top ten list for Washington Tom mentioned in post #3.

300.11, securing cables to other raceways or cables is another big one.

Guys in these parts are notorious for leaving 2 or 3 feet of wire at ceiling openings of every kind. I've heard it called "service loop" more times than I can remember.

In short, stapling is the most common violation I see. Staples too far apart, too far from boxes, too close to edges of lumber...

I have to recant what I said, sitting in a new restaurant in town, never seen so many floating j-boxes! At least it’s emt, and not romex strewn through the open ceiling! Exit light is hidden on the wall above the door. We apparently don’t have a fire marshal either!

 

[hillbilly1]

Every one of those boxes is floating! Exit light is barely visible above the door!

Maybe this picture is a little clearer.

What’s the deal with the 567 different bulbs? Maybe a trend in some areas?

As a plug and receptacle guy this is the most common one that I see.

406.7(B) Connection of Attachment Plugs.

NFPA 70 — National Electrical Code (2020)

Attachment plugs shall be installed so that their prongs, blades, or pins are not energized unless inserted into an energized receptacle or cord connectors. No receptacle shall be installed so as to require the insertion of an energized attachment plug as its source of supply.

Worst offender - Water/Water Treatment Facilities and Equipment

In my hometown, I can usually tell the most violated code sections by what my suppliers stock.

For instance, no one here stocks schedule 80 PVC, or rain tight compression connectors. And only one supplier stocks WR receps. I find myself ordering material on a regular basis that should be in stock.

I call that what inspectors aren't calling out, or that no inspections are happening.

Oddly enough, I only see "5",,,,, "6" ,,,,,, or maybe "7" different types of bulbs at most,,,,,

I am exclusively an industrial I/E tech, so my observation only applies to industrial settings. The single most violated code is the NFPA 79 "Electrical Standard for Industrial Machinery", Section 13.5.9.2 "Motor Connection Boxes" states: "Electrical connections at motor terminal boxes shall be made with an identified method of connection. Twist-on wire connectors shall not be used for this purpose".
