How well do you know the Code? Think you can spot violations the original installer either ignored or couldn't identify? Here's your chance to moonlight as an electrical inspector and second-guess someone else's work from the safety of your living room or office. It's your turn to identify the violation.

Maybe it was just bad timing or a mere coincidence that these photos were taken at this particular moment on the job, but in any case it makes for a great discussion. Let’s begin by trying to figure out what’s going on here. It appears as though some circuits are being re-routed or re-located.
I noticed that many of the equipment ground wires of the NM cables are just floating in the air or are back-wrapped on the cable. Leaving the ground wires disconnected can create a real shock hazard. Even if these wires are just temporary, Sec. 590.4(G) still requires the continuity of the equipment grounding conductors to be maintained whether a box is installed or not. On construction sites, Sec. 590.4(G) does allow splices without the use of boxes.
Section 590.4(J) requires cables to be supported in a manner that prevents physical damage to the cables. I think these cables could use some support, considering the only thing holding them up right now are the splices! Putting strain on electrical connections is never a good idea. Some protection should also be provided where the NM cables are passing through the floor. Section 590.4(H) requires that flexible cords and cables be protected from accidental damage. Of course if this wiring is intended to be permanent, then the installer should hire a qualified electrician and completely start over.
