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.
Hint: (Jack) hammer time
Find the Answer
Get the jackhammer! We’re going to need it to get inside this box.
One side of this box cover has been engulfed in concrete, making it virtually impossible to get to any splices inside unless you break up enough of the concrete in order to remove the cover. This is a violation of Sec. 314.29, which requires wiring in boxes, conduit bodies, and handholes to be accessible without needing to excavate sidewalks, paving, earth, or other material used to establish the grade.
Another concern I have is the use of EMT with this PVC box. Section 314.3 does not permit metal raceways or metal cables to be used with nonmetallic boxes unless internal bonding means are provided between all entries.
To wrap this up, I have one final concern with the use of a set-screw type EMT connector at this location. Because this was a wet location, the use of set-screw type EMT connectors is a violation of Sec. 358.42 and Sec. 314.15 because these connectors are not listed for use in this location.
