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.

Thanks to Brad Endsley, a senior maintenance mechanic with Ormco Corp. in Glendora, Calif., for sharing this photo with us. He took this picture while walking around some fair grounds. He says, “I looked over, and saw this 120V receptacle, and just had to take a picture.”
The first problem I will point out is the use of liquidtight flexible nonmetallic conduit (LFNC) with PVC connectors and conduit bodies. Section 356.42 of the 2014 NEC requires LFNC to be used only with fittings listed for use with LFNC. PVC connectors and conduit bodies are not listed for this use. This also violates the requirements of 110.3(B) because these wiring methods are not listed to be used in this manner. Section 356.12(1) prohibits LFNC from being used where subject to physical damage. This installation has obviously been banged around and seen some abuse because the raceways have completely separated from the conduit bodies. For this wet location, the rules of 406.9(A)(1) have also been violated because a “weatherproof when closed” cover was used instead of a cover that is weatherproof whether or not the attachment plug cap is inserted into this 15A or 20A receptacle. In addition, the separated raceways could allow moisture and water to enter the enclosures and contact energized parts, creating a real shock and fire hazard.
